Tutorial on how to use the ADC Module of the ATmega328P

VFD tubes are a good alternative to Nixie Tubes, especially in retro clock projects. Read about how they can be used with an Arduino.

Make your projects colorful.

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.

An Arduino code that displays on a small 0.98" OLED SSD1306 Date/Time and also calculates and displays Salat Time for a given town

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.

This LED Display Module can works with two-color LED matrix in two sizes (large and small), as well a 7 segments x 4 digits.

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