After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM.

Connect the 2N2222 transistor to the pin3 of the Arduino with a resistor connected to the base of the transistor and collector terminal to the 5V of Arduino Uno. Connect a small bulb between the ...

Pulse-Width Modulation (PWM): PWM regulates fan speed using a low-frequency signal (~30Hz) with varying duty cycle. The PWM signal controls how much power the fan receives, ... Fig. 3: Actual-size PCB ...

To create extra channels of 16-bit PWM using the available 4 channels of 8-bit PWM on ATmega328P, this project requires the use of Timer0 and Timer2 in the microcontroller. However, since Arduino uses ...
