PIR Sensor and Relay Switch to turn on a Light

Ever wonder how a motion detector is used to turn on a light? Take a look at this graphic (made with Fritzing). It shows the circuitry that uses an STM32F103C8T6 microcontroller to control a PIR sensor and relay switch to turn on a Light. Get the Fritzing source code for the above image HERE (in …
