Morse-Talk helps non-verbal individuals communicate via Morse code. Arduino IDE code converts Morse to text on LCD. Python (VS Code) handles text-to-speech via Bluetooth and triggers GSM emergency ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

If you’ve been watching Nintendo Switch 2 news like a hawk for the past few weeks, you may have spotted leaks about the new and improved Joy-Con controllers, and wondering just what an IR sensor is.

Infineon’s PASCO2V15 CO2 sensor is a compact and precise carbon dioxide sensor that uses photoacoustic spectroscopy (PAS) leveraging its built-in microphone and IR emitter to detect CO2 levels by ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

STMicroelectronics’ STHS34PF80 ultra-low-power IR sensor with micromachined thermal transistors detects up to four meters without an optical lens. Developed as an alternative to passive infrared (PIR) ...

The smart car parking system uses an ESP32 microcontroller, an IR sensor, a servo motor, and an Arduino Cloud account to efficiently manage parking spaces, reduce traffic congestion, and improve air ...
