This project utilizes an IR remote to control home appliances connected through a relay module to an Arduino Nano. The system decodes the IR signals, turning the appliances on or off based on the ...

This project demonstrates how to create an anti-sleep alarm system for drivers using an Arduino Nano and a Relay Module. The system detects signs of drowsiness or fatigue in the driver and triggers an ...

In my case I have used only 3 x 330Ω resistors, 3 leds and a TSOP4838 IR receiver module. You must check the datasheet before use the IR module to see which pins connect to the power supply and which ...
