Audio Amplifier using Op-Amp: Electronics Project

This article provides an information about how to make an audio amplifier using an opamp. We will also try to explain the working of this audio amplifier using an opamp.

How to make audio amplifier using opamp

We have already studied some important applications of the operational amplifier such as op-amp comparator, op-amp integrator in the previous articles. Today we are going to learn another important application of op-amp as an audio amplifier and its working.

We know that the output of most of the communication receivers is the audio amplifier. Important characteristics of the ideal audio amplifier are listed below.

  1. High gain.
  2. Distortion should be minimum in the audio frequency range. (20Hz to 20KHz)
  3. Input resistance or impedance should be very high.
  4. Low output resistance to provide optimum coupling to the speaker.

If we use the operational amplifier in the audio amplifier, then it will cover all the characteristics listed above so as to make an ideal audio amplifier.

Circuit diagram

The following figure shows the circuit diagram of the audio amplifier using operation amplifier.

Working of audio amplifier

It should be noted that the op-amp is supplied only from +V volt power supply (usually 5V power supply), the –V terminal is grounded. This arrangement is made so as to get the output in the range (+V-1) volt and +1 volt. In audio amplifier coupling capacitor (Cc2) is used between the op-amp and speaker. The coupling capacitor is necessary to reference the speaker signal around the ground. The capacitor Cs is included in the Vcc line to prevent any transient current caused by the operation of op-amp from being coupled back to Q1 through the power supply.

DTMF Based Load Control System (Home Automation): Electronics Project

This project works on the principle of DTMF (Dual-tone multi-frequency). This circuit can be used to control or on/off the load i.e. electric equipment like a fan, bulb, water pump, etc.

We know that in industries, loads are distributed over large distances, and it is not convenient to operate all those equipment time to time and it is also time to consume.

Also in agricultural fields, water pumps and other electric systems are spread over the large area and it is hard to operate these systems to farmers. We can use this circuit in the home too, therefore this can also be called as DTMF based home automation project. Keeping all these problems in mind, a DTMF based load control system is designed as follows.

In DTMF based load control system, a cell phone (mobile) is connected to the circuit from its audio output (audio jack) to receive the tone generated by the operator mobile. Whatever audio signal (in the form of frequency) is received from mobile then decoded (to its digital code) by the use of DTMF decoder which is one of the main parts of the project. Then this digital code goes to 8051 microcontrollers which on/offs respected relay to control that electric equipment. a relay driver IC is interfaced with the microcontroller to actuate the relays.

Components required:

Sr. no Equipment Quantity
1 IC 8051 MC 1
2 MT 8870 DTMF IC 1
3 Crystal (3.579545mhz) 1
4 VOLTAGE REGULATOR 1

Mobile Incoming Call Indicator: Electronics Mini Project

Hello friends, are you searching for one good mini project for your submissions? If your answer is yes, then your search will end here. Today I am going to make a circuit that will indicate an incoming or outgoing call or message from your mobile phone. Yes, you can do such awesome mini project with some simple electrical components within no time. Let us start making our “Mobile incoming call indicator” mini project.

Components Used

  • IC 1 = NE555 (Timer IC)
  • Resistors
  • Capacitors
  • Transistor : Q1 = BC548
  • LED
  • 6V DC Battery
  • Diode: 1N5819

Description

In this mini project, we are going to make a simple circuit that will detect a mobile phone. In this mini project, we have used a LED which will glow instantaneously when a mobile phone rings.

Whenever your mobile phone receive an incoming call, it will activate a transistor in the circuit. The coil L1 acts as an antenna which will sense the oscillations. These oscillations then are given to the base of transistor Q1 thus activating the transistor. As the output of transistor i.e. collector is connected to the IC 555 which get triggered and glows the LED connected to its output pin. Thus when LED glows we can conclude that there is an incoming call surrounding the circuit.

Water Level Indicator Circuit: Electromics Mini Project

Today we are going to make a project which will detect the preset water level and when water is reached to this level it will generate a sound.

Objective:

The objective of Water Level Alarm Circuit is to generate a sound with the help of buzzer when a water level in a tank reached to its preset level (Predefined mark).

Components Required:

Following are the required components for making water level alarm circuit:

  1. IC NE555 (Timer IC)
  2. Resistors: R1 = 1K; R2 = 100K;
  3. Capacitor: C1 = 2.2uF (15V)
  4. Buzzer
  5. 3V DC battery

Circuit Diagram:

Water Level Indicator Alarm Circuit

Description of Water Level Indicator

Here is the simple water level alarm circuit using 555 timer IC which will produce an audible sound when the water level reaches to its preset level. This circuit uses 3V DC power supply. Therefore this circuit is quite handy to use.

This circuit of water level alarm is based on the astable multivibrator which is wired around IC1 (NE555). The operating frequency of this astable multivibrator depends upon the values of capacitor C1, resistors R1 and R2 and the resistance across probes at A and B. when there is no water up to the level of probes, because of open circuit astable multivibrator will not produce any oscillations hence the circuit will not produce sound. When the water reaches the level of probes, the circuit will be completed and some current flows through the water. Thus astable multivibrator produces oscillations proportional to the values of C, R1, R2 and the resistance across the probes. Now the buzzer will beep to indicate that the water is reached to its preset level.

Notes

  •  Probes can be made of two insulated copper or aluminum wires.
  •  Preset level means the level that you want to detect the water in the tank.
  •  Place the probes to a preset level, so that it will close the path and generates sound using the buzzer.

Air Flow Detector Circuit Electronics Project

This is a simple and useful electronic mini project for the beginners. In this project, we are going to detect the flow of air present or not. Air flow detector circuit is used for the detection of the flow of air. This circuit can be used for the visual indication of the rate of air flow. This circuit can also be used for detecting the presence of air flow in the given space or not.

Components used

In this mini project about detecting the rate of air flow, we will require following components:

  1. IC 7805
  2. Capacitor: 47uF (15V)
  3. Resistors: R1 = 100 Ohm, R2 = 470 Ohm, R3 = 10K, R4 = 100K, R5 = 1K
  4. 12V DC power supply
  5. OP-AMP LM339
  6. LED
  7. The filament of an incandescent bulb as a sensing element. (See this video for extracting filament from bulb: https://www.youtube.com/watch?v=X5E1n0uLepM)

Circuit Diagram

Air Flow Detector Circuit Diagram

Description

As mentioned earlier, we are going to detect the rate of air flow with help of visual indication using LED. In this project, we are using filament of an incandescent bulb as a sensing element of our circuit.

When the intensity of the air flow is minimum or if there is no airflow, the resistance of the filament of the incandescent bulb will be low. Similarly, when the air flow is maximum the resistance of the filament will be high. This is because filament of incandescent bulb has a negative temperature of a coefficient. That is when the temperature of the filament increases the resistance decreases and vice versa.

Now in our case when there is maximum air flow the heat will be decreased due to that air flow and its resistance increases. This difference in resistance will produce a different voltage drop across the filament of an incandescent bulb. This difference in the resistance will be picked up by the opamp (LM339) and it will produce variations in the output. That is the output will be proportional to the airflow.

Street Light Circuit Using LDR Electronics Project

In this mini project of the street light circuit using LDR, we are going to operate street light using a light dependent resistor (LDR).

Objective

The purpose of this mini project is to switch off the street light in the day and switch on the street light in the night.

Components required

Following are the components which we are going to use for this mini-project of the street light circuit using LDR:

  1. LDR (R1)
  2. Resistors : R2 = 100K, R3 = 1K, R4 = 1K
  3. Transistors: Q1 = BC 107, Q2 = SL100
  4. K1 = SPDT relay
  5. 230V Lamp
  6. 9V battery
  7. Fuse (optional)

Description

The following figure shows the circuit diagram of the street light controller using LDR. Here we have used a 230V lamp which will turn on in the night and get turned off during the daytime.

Street Light Controller Circuit Diagram
Street Light Controller Circuit Diagram

Light dependent resistor i.e. LDR is the main component used in this mini-project. We know that the resistance of the LDR decreases as the intensity of the light increases and vice versa. The Same principle is used here. When there is the presence of light the resistance of LDR will be low. So the voltage drop across the pot R2 will be high, which keeps the transistor Q1 on. The collector of Q1 (BC107) is coupled to the base of Q2(SL100). So Q2 will be OFF and so do the relay. The bulb will remain OFF.

Similarly at night the intensity of light decreases and resistance of LDR increases. Therefore the resistance of pot R2 decreases below 0.6V. This makes transistor Q1 OFF which in turn makes Q2 ON. The relay will be energized and the bulb will glow.
