Controlling DC Motors Using Python With a Raspberry Pi. Welcome to the MikroElektronika Compiler Quick Start Guide. SwitchPin(int pinId, int status) – an HttpPost action which allows me to select a GpioPin with number pinId, and set it to a value of status (which is either 1 or 0,. In short, GPIO enables you to do physical computing. These pins are directly connected to our Broadcom chip, so this is a "proceed at your own risk" tutorial. 3, but with one big difference – built-in WiFi!More specifically, this giant upgrade.
