Espressif yourself.

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 ...

Imagine a world where microcontrollers (MCUs) and development boards operate without batteries. Energy-harvesting technology now makes this a practical ...

Yeckel] recently put the finishing touches on an ambitious implementation of a simple D-STAR (Digital Smart Technologies for Amateur Radio) transceiver using some very accessible and affordable ...

Back in school, I spent more hours than I can count hunched over an Arduino Uno – blinking LEDs, wiring up sensors, and building clunky robots that barely worked but felt like magic. The Uno was ...

While fuel cells generate clean energy, fuel cell sensors generate precise measurements and are a gold standard for breath alcohol analysis.

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

Nagy Krisztián] had an Intel 286 CPU, only… There was no motherboard to install it in. Perhaps not wanting the processor to ...

In recent years, integrated platforms equipped with microcontrollers (with Arduino probably being the best-known brand) have been gaining popularity.

The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...
