555 Bonus

PWM Servo Motor Control

To complete the bonus you will;

• understand what a servo motor is
• understand a pwm (pulse width modulated) signal and how it is used to control the servomotor
• understand how the astable multivibrator that you just made works
• understand how to modify the astable multivibrator that you built to create the desired pwm output at pin 3.
• given the components; layout, etch, solder, and test (demonstrate) servo motor driver
• create calculations to show the expected waveform properties at the output of pin 3

What to hand in;

• demonstrate your circuit for function. (run a servo motor)
  • Supporting documentation should be available. Circuit should be correctly identified on the pcb.
• hand in calculations
• there could be a test, quiz or verbal explanation(s) required to demonstrate the understanding of the circuit
