Play Super Mario Bros theme song on a piezo buzzer! It’s very simple and fun, and great as a beginner Arduino project.

Arduino and NeoPixel Tutorial appropriate for a beginner.

Failed but still teaches a lot.

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

Connect I2C Character LCD Display to Arduino and program it - quick and easy!

Driving a Single Digit 7 Segment LED Display requires 8 of an Arduino's 20 or so I/O pins. Using a 74HC595 shift register only requires 3.

In this tutorial, I will be showing you how to get started with the small 0.91 and 0.96 I2C OLED displays using Arduino and NodeMCU.

Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor.

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

I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.

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

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

Control 256 relays! Seeing is believing!

This doorbell can operate without touch the switch.

Imitate musical instruments and make music with an Arduino and only few external components!

Publish your Arduino input in real-time so it can be accessible on the internet without taking care of server side.

Make your projects colorful.

Connect Stepper Motor to Arduino and control it with Rotary Encoder - Quick and Easy!

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

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

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