Title: 555 PWM DC Motor Speed Controller
NE555 Timer used as PWM generator to control motor speed.
How it works:
- 555 in astable mode with variable duty cycle
- Potentiometer controls speed from 0% to 100%
- MOSFET switches the motor/LED load
- Flyback diode protects MOSFET from motor spikes
Components:
555 Timer, 2x 100Ω, 1kΩ, 10k Pot, 1uF Cap, N-MOSFET, 1N4007 Diode, DC Motor/LED
Note: Connect RES pin directly to 9V. Works on 9V battery.
