Unlock the secret to storing data on the ESP32 without using EEPROM. In this video, you'll learn how to keep your variables alive even after your microcontroller goes to sleep or reboots. We'll ...
Volos Projects recently showcased an easy-to-reproduce, inexpensive DIY ESP32-S3 Internet radio based on a Waveshare ESP32-S3-LCD-1.54 development board ...
You can buy all kinds of conventional clocks that have hands and numbers for easy reading. Or, like [Fabio Ricci], you could build yourself something a little more esoteric, like this neat shadow ...
