The circuit diagram of the LED flasher using Arduino is shown in Fig. 1. The circuit is built around Arduino Nano board (Board1), twenty coloured LEDs (LED1 to LED20) and a few other components. Fig.

At the time of working on this project, I had been practicing with Arduino and Atmel ATmega128 microcontrollers (Microchip Technology has since bought Atmel). I wanted to use the Arduino to toggle a ...

This library is designed to make the use of LEDs as simple as possible. After creating the LED and asigning a port number, the state simply can be changed to on, off, blink or flash. When constructed ...

So this is how Charlieplexing technique can be used to control many LEDs using fewer Arduino pins. You can use this method to control more number of LEDs. For example, if you want to control 20 LEDs, ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

Now run the install_arduino.m file. This code will correctly install and save the path of the Arduino support package. Open the source code file (Illumination001.m) for this project. Edit the line ...

We previously used an 8x8 LED matrix with many boards to control the text displayed over it, today we will use the P10 display with Arduino. In this tutorial we are going to use a 32x16 LED dot Matrix ...
