In the microcontroller era today, Arduino is more than just a tool to accomplish ... the switching when it detects a moving target. Most Digital PIR sensor modules have three connector pins: Vcc (5V), ...

Furthermore, the vacant solder pads near the three-pin interface header is for mounting a light-dependent resistor (LDR ... Arduino IDE compatibility. The code is an Arduino project for the Digispark ...

Get close enough to this raven and you’ll set off the PIR sensor, which triggers lighting ... This bird’s brain is an Arduino Nano, which is protected from the 12V supply with a boost converter.
