Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

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 ...

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 ...

This repository documents an embedded systems mini-project: a Arduino light Sensor Monitoring System designed to demonstrate core skills in circuit design and microcontroller programming. The system ...

A button connected to the Arduino allows manual toggling of the relay state (ON/OFF). The button uses an internal pull-up resistor for stable input and includes a debounce mechanism to prevent false ...
