This project allows you to remotely control home appliances using an IR remote and an Arduino Nano. With this setup, you can manage up to 4 devices (such as lights, fans, etc.), and the system saves ...

IR (Infrared) communication is simple, low-cost, and widely used wireless communication technology. IR light is somewhat similar to the visible light, except that the wavelength is slightly longer.

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 ...

As you might have noticed, the 38-KHz pulse generator is built around the evergreen timer chip NE555P (IC1). Here, the RC components (R5-C3-P1) set the astable frequency to drive the infrared light ...

An infrared sensor is an electronic module that is used to detect the certain physical appearance of its surroundings by either emitting and/or detecting infrared radiation. IR sensors can also sense ...

We’ve already covered inexpensive offline voice recognition modules based on US516P6 or TW-ASR ONE microcontrollers that allow people to add smarts to their projects without a network connection for ...
