555 Integrated Circuit Servo Tester (Includes Printed Circuit)

In this tutorial we will see how to assemble a servo tester with the legendary 555 integrated circuit. This circuit generates a PWM (pulse width modulation) pulse to be able to move a servo in one direction or another.

It is a simple and didactic circuit, with very economical electronic components and easy to find in any electronics store.

This circuit operates from 7 to 9 volts of DC current.

About integrated circuit 555

Its entry into the electronic world was in 1972, the integrated circuit 555, remains one of the most selling integrated circuits. Its success and popularity is in its great flexibility for electronic designs: electronic developers can configure it different ways. The 555 is a very economical integrated circuit. It has a wide variety of applications, in which we can highlight:

In astable mode, it produces a repetitive timing pulse that has a frequency defined by two resistors and a capacitor.
