Now if you look at the datasheet of the 2n2222 NPN transistor you will find the 2n2222 base voltage should not exceed 6 volts. As you can see in the circuit diagram I have used a 2n2222 NPN transistor. We can use a transistor with the LM741 IC.

So it means we will need some kind of driver to control the relay. The relay I have used in this circuit needs around 32milliamps. But if you look at the datasheet you will find that the output current of the LM741 IC is 25milliamps which is not enough to turn on a 12v relay. Now the next step is to use this output voltage to control a Relay which can be used to give signals to the controller. So when the output is high we get around 12 volts.Īt this point, we are able to differentiate between the “two states, Light is falling on the LDR or not” and accordingly we get 0 volts and 11 volts approximately. The output voltage of the LM741 IC is not exactly 12 volts it can be around 10 to 11 volts. V1 > V2 and the output will be low if V1 V2 the output get High, and at the output, we get voltage which is approximately equal to the input supply voltage which in our case is 12 volts. V1 and V2 will be compared using the LM741. V1 = Reference voltage which is coming from the Variable resistor. We have to voltages to compare, one voltage is coming to form the LDR and the other is the reference voltage set by the potentiometer or variable resistor.

Two 470 Ohm resistors are connected in series with the 100k variable resistor, which protects the circuit from the short circuit. This variable resistor is used to set the reference voltage on the Non-inverting input of the LM741 Op-Amp IC. The voltage which is fed to the Inverting input of the LM741 IC is compared with the voltage which is coming from the R3 which is a 100K variable resistor.

As you can wire from the middle of the LDR and 10k resistor is connected with the Inverting input pin of the LM741 Op-Amp IC. The resistance of the LDR changes with the amount of light falling on the LDR. As the amount of light falling on the LDR changes so the resistance changes due to which we get variable voltage. The LDR and 10k resistor makes a voltage divider circuit. The LDR “Light Dependent Resistor” is connected in series with a 10 kilo Ohm resistor. In the above circuit, the LM741 Operational Amplifier is used as the voltage comparator. I would appreciate your support in this way! I may make a commission if you buy the components through these links. We will be making our own H-bridge to control the direction of the dc gear motor. Today the solar trackers are used throughout the world, the solar tracker that we are going to make today is best as it’s cheap and is able to rotate heavy panels as we will be using the relays, and as you know relays can bear larger currents.
