This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

LilyGO has recently released the T-Display S3 Pro LR1121, a new ESP32-S3 development kit with a Semtech LR1121 transceiver ...

We think of crystals as the gold standard of frequency generation. However, if you want real precision, you need something either better than a crystal or something that will correct for tiny errors — ...

This IoT-enabled system continuously tracks a bedridden patient’s vital signs (ECG waveform, heart rate, and body temperature) from anywhere in the world. By combining a microcontroller (Arduino) with ...

If you’ve got a decent CRT monitor, you can usually adjust the settings to make sure the image scans nicely across the whole display. But what if you could rotate the whole image itself? [Jeri ...
