Servo Motor Controller Circuit

555 Modes

Basically 555 timer IC can be used in 3 modes 1. Monostable Mode 2. Bistable Mode 3. Astable Mode.

In this blog we discussed about how 555 Timer can be used as Servo Motor Controller using Astable Multivibrator.

555 Timer Pin Diagram

PIN 1 is Ground Pin, Pin 2 is the Trigger Pin, PIN 3 is Output Pin, Pin 4 represents Reset Pin, Pin 5 is the Control Voltage, PIN 6 is Threshold, PIN 7 is the Discharge PIN and PIN 8 represents Power Supply or Vcc.

555 Timer Internal Architecture

555 Timer is divided into 5 parts. First part is voltage divider circuit, second comparator block, third flip-flop circuit, fourth discharge circuit and last output driver circuit.

Simple Servo Motor Control Circuit Diagram

PIN2 is connected to PIN6 and a capacitor(Here we used 0.1microF) is connected with PIN2 & Ground. PIN6 is also connected to PIN7 with a 1Mohm resistance and a Diode. PIN7 is connected to PIN8 with a 100Kohm variable resistor as PIN8 is the Power Supply or VCC. Servo Motor’s Orange wire is connected to PIN3, Red wire is connected to Positive and Brown wire is connected to Ground.
