Interfacing a 128*64 OLED display with Arduino

This tutorial is about interfacing an OLED display with Arduino. OLED (Organic Light Emitting Diode) displays are made by placing a series of thin organic films between two conductors. When electrical current is applied, a bright light is emitted. These displays are more effective then LCD displays. OLED displays are called organic as they are composed of carbon and hydrogen. They are also very efficient and do not contain any bad metals. Using a...

Interfacing an 8x8 Matrix with Arduino, using MAX7219

When combined together in a symmetric manner, multiple LEDs can be used to display messages or patterns which look very aesthetic. Commonly, LEDs are arranged in the pattern of a square matrix, as it is easy to program and convenient to use. This tutorial utilizes an 8x8 matrix to display scrolling text. Components required for this project: 1- Arduino Any Arduino would do for this project. 2- 8x8 LED matix MAX7219 module This LED matrix is...

Ultrasonic sensor interfacing with output display on 8x32 LED Matrix

The HCSR04 ultrasonic sensor can sense the distance between itself and the object in front of it. It uses the formula d=(v*t)/2 to calculate the distance. We can display the output on an LED matrix, rather than viewing it on the serial monitor. This makes the project more portable and we can avoid having it attached to a computer for just viewing the distance. Here’s a tutorial on how to use the LED matrix. This tutorial will involve not only...
