Window alarm sensors are an essential part of home security systems, alerting you to unauthorized entries by monitoring window openings, glass breaks and motion. Each window alarm sensor type serves a ...
There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...
At Hardware Pioneers Max 2026, it was great to bump into Arduino's Field Engineering Evangelist, Julián Caro Linares, who introduced me to a smart mirror... It runs AI locally via the new Arduino ...
In this tutorial, you will learn how to send WhatsApp messages from Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex WhatsApp ...
These meters generally use a sensor to relay the flow measurements to a reading device. Nearly all types of flowmeters, from ultrasonic to turbines, are offered with pulse output flow signals. Sensing ...
The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...
