Servo motor is a DC operated motor and it is available in various sizes and powers. Generally the servo motor used in basic projects, is named as micro servo motor. It is of small size and low power rating. But as I stated earlier that it needs dc supply to operate but it also needs a continuous pulse train to operate and this pulse is commonly generated by some sort of timers or micro controllers. Since my today’s project tutorial (Angle Control of Servo Motor using 555 Timer in Proteus ISIS) is of basic level so, we will be using 555 timer to generate the continuous pulse train or PWM. Now let’s move towards hardware but dear friends, always remember that to become a technical person, you must have to perform technical work by yourself.
A 555 timer is an 8 pin IC. Pin # 6 is called threshold pin and for 555 timer threshold level is 5 volts.
Since in this tutorial (Angle Control of Servo Motor using 555 Timer), we are going to get full deflection of motor so, we have inserted 2 switches in the circuit. The complete circuit will look like:
Switch # 1 will rotate the servo motor to 180 degrees in anti-clockwise direction. We will press the button only once and when the motor completes its rotation, it will automatically stop.
If you have connected the components in correct order and when you will run it, the exact simulation will look like as shown:

Alright Friends, that's all for today, In the coming posts, we will discuss few more such projects. Till than, take care and be safe !!! :)
