This circuit drives a motor with a trimmer and reduces the speed to zero when the trimmer is in mid-position, the current is limited to 200mA and the voltage across the motor is less than 6v (only DC Motor).
The circuit works with the principle of Pulse Width Modulation (providing powerful bursts of current to the motor, to create a High/Low RPM under load) and both Forward/Reverse RPM by the H-Bridge, the main components of this circuit are 2 NE555, a 100K potentiometer, a DC motor and 9V DC power supply.
As you can see in the video, you start from a central position of the potentiometer, turning it to the right, or to the left, you choose in which direction to make the motor work.
● Components:
- 2x NE555 IC
- 1x 1KΩ Resistor
- 1x 330Ω Resistor
- 1x 104 Ceramic Capacitor
- 1x 100KΩ Trimmer
- 2x 1N4148 Diode
- 1x DC Motor (3/6V)
- 1x On Off Switch
- 1x LED (as pwr LED)
