PWM on raspberry pi. With only one hardware PWM pin on Raspberry Pi it can be quite a problem with Arduino users like me. There are various hardware solutions available to overcome this problem. Many ADC(analog to digital converters) IC are available which can be interfaced via I2C bus. In this post I will be using WiringPi library which can bit-bang any GPIO pins and generate PWM signal.

Raspberry Pi PWM Tutorial - Circuit Digest

PWM Pulse Width Modulation (or PWM) is a technique for controlling power. We use it here to control the amount of power going to the motor and hence how fast it spins. The diagram below shows the signal from the PWM pin of the Raspberry Pi. Every 1/500 of a second, the PWM output will produce a pulse.

Raspberry Pi 2 でPWM制御 – 桜のはなびらブログ

The Raspberry Pi PWM clock has a base frequency of 19. 2 MHz. This frequency, divided by the argument to pwmSetClock(), is the frequency at which the PWM counter is incremented. When the counter reaches a value equal to the specified range, it resets to zero.

To demonstrate PWM on the Raspberry Pi, first connect the Pi GPIO pins to an LED as shown in the diagram below. The longer lead is the anode + and connects to an 270 ohm resistor (or near 270). The slightly shorter lead of the LED is the cathode and connects to ground, pin number 6 of the Raspberry Pi (3rd pin from left on outside row).
