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 ...
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 ...
internet inspired esp-01 (esp8266) IO expander. This uses DIP (socket and replace if you oops) 74xx595 and 74xx165 chips to give you 16 inputs and 16 outputs from an esp-01 Why not just use i2c? WELL, ...
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 ...
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 ...
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 ...
[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 ...
