An Arduino EEPROM dump utility class have been added to the repository https://github.com/ctheroux/Arduino/ . A typical output looks like:

The Arduino UNO R4 Wi-Fi is a great addition to the Arduino family. A fun little board to play with. The Arduino UNO R4 Wi-Fi could not connect to my

This is a simple human interface project for Home Assistant. It helps me remind doing 2 daily tasks. Using Home Assistant automation, it lit a LED at a given time

The ESP8266 can yield a 163 kHZ wave using the Arduino IDE and writing the code in C.  The code used is: int pin = 5; void setup() { pinMode(pin, OUTPUT);

An ESP8266 running NodeMCU can yield maximum frequency of 1.44 kHz with a duty cycle of 61%.  The wave form is given below.  The code used to perform this test is: pin =

It can be sometimes challenging to regain control of the NodeMCU running on a ESP8266 when init.lua has a tight loop in it.  To do so,  first, download esptool.py from GitHub.

I have written a page that contains many useful links about the ESP8266 platform.  You can display this page either using the top menu option “ESP8266 Resources” or by cliking

A remarkable book about the ESP8266 is freely available.  It can be downloaded from Kolban’s book on the ESP8266.  It contains more than 300 pages of information.  This book is a
