Control a Cooling Fan on a Raspberry Pi 3: Add a fan to a raspberry pi 3, with control to turn it on and off as required. In this Raspberry Pi PWM tutorial we will talk about getting PWM output with Raspberry Pi. Connect the Raspberry Pi with the LED and camera according to the following figure. Before you do anything with the GPIO header though, make sure that your Raspberry Pi board is turned off and unplugged from power. 3V, while the switch on pin 24 is tied to ground. Fig, 5 Fig. The full contents can be seen below. Here's the pin diagram for the PDIP/SOIC package: For this microcontroller to operate, you need a crystal oscillator connected to pin #16 and pin #15 and 22 pf capacitors from these pins to ground (see schematic below). Since, it is a portable device, I need to power the Pi-3 using batteries (18650 or Lipo batteries).
