I’m a big fan of the ESP-01 Wi-Fi modules. Because I’ve done a couple of Wi-Fi projects, rather than fiddle with pin headers and jumper wires while programming, I decided to get one of those generic ...

The PSLab provides an array of test and measurement instruments for doing science and engineering experiments. Its built-in instruments include an oscilloscope, a waveform generator, a frequency ...

PCF8574 library. i2c digital expander for Arduino, Raspberry Pi Pico and rp2040 boards, esp32, SMT32 and ESP8266. Can read write digital values with only 2 wire. Very simple to use and encoder support ...

ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such ...

What a time to be alive! The range of things you never knew you needed but absolutely must have expands at a breakneck pace, such that it’s now possible to pick up a belt buckle with an embedded LED ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...

IoT and home automation have come a long way since they first gained popularity in 2014, thanks to the debut of a game-changing IC called the ESP8266 by espressif systems. Today we know it as the ...

[Matheus Garbelini] just came out with three (3!) different WiFi attacks on the popular ESP32/8266 family of chips. He notified Espressif first (thanks!) and they’ve patched around most of the ...

The development of energy and cost efficient IoT nodes is very important for the successful deployment of IoT solutions across various application domains. This paper presents energy models, which ...
