Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...
Before we get started it is important to understand that there two types of nRF24L01 modules available in the market one is called just nRF24L01 and the other is called nRF24L01+ PA+LN. While both the ...
Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...
