Measure rotation speed (RPM) with Optocoupler and Encoder disk and Arduino - Quick and Easy!

FreeRTOS, simple, easy, robust, and optimised for Arduino IDE. Using FreeRTOS Semaphores to share and protect physical resources.

Use FreeRTOS (simple, easy, robust, & optimised for the Arduino IDE) to reduce the power required for battery or low power applications.

The software library to calculate moon age, sunrise and sunset time.

Easily connect Arduino boards at a great distance over RS485 with Visuino.

Build a treasure chest or use an existing storage box, attach a push-button quadrature rotary encoder (endless spinning dial) and lets go!

ESP8266 Arduino Programming Tutorial - Easy to learn, step by step.

How to make projects more robust and reliable using drivers ULN2803, UDN2981 and PNP transistors.

In this project, I am going to make a LAN cable tester with just a few basic electronics components. It cost me just a bit over $3.

Three different way of connecting a push button with an Arduino microcontroller.

Using the built-in Arduino EEPROM to save and restore values - Quick and Easy.

This is my 4th tutorial on how to drive a RELAY (not a relay module) with an Arduino.

It's an elevator with automatic doors. The code has two FSM, one for the motor that makes it go up and down and one for the automatic door.

Embedis is a library for creating simple embedded key-value servers using non-volatile storage like NVSRAM, FRAM, FLASH, or EEPROM.

H3LIS331DL is a low-power high performance 3-axis linear accelerometer belonging to the “nano” family with digital I²C serial interface.

In this tutorial, I am going to talk about the PCF8574 8-bit GPIO port extender.

I built the right and left mouse buttons with wall switches.

This circuit allows for one thermistor input and will output up to four similar values using digital pots.
