To generate the signal current for this experiment i used the. Control dc motor with npn transistor arduino pwm gpl3 an easy way for controlling the rotation speed of a dc motor by using pwm signal from arduino and a npn transistor.
In this instructable i will be focusing on npn transistors.
Using lower threshold mosfets designed for interfacing with ttl and cmos logic gates that have thresholds as low as 1 5v to 2 0v are available. A simple introduction to transistors and pwm pulse width modulation step 1. A driver circuit is also very useful if you are experimenting with pulse width modulation pwm techniques where the goal is to control the brightness to create a dimming and fading effects. Up until 9 4 volts the code works perfectly to do pwm on the circuit but it only has a current of 30 to 40 ma rather than the full 60 ma.
