Serial seven segment LED display shield

Seven segment LED displays are brighter, more attractive, and provide a far viewing distance as well as a wider viewing angle compared to LCD displays. This project describes a serial seven segment LED display shield for Arduino Uno or compatible boards. The shield consists of eight 0.56″ seven segment displays that are driven by one MAX7219 chip. The shield also features a light dependent resistor (LDR) to ...

Revive Old Drive-In Speakers with a Modern LED Twist

When I was a kid we went to the drive-in theater to see movies like The Legend of Boggy Creek and Evel Knievel. I loved those movies but I remember just as vividly those retro-cool metal speakers that entered into our car for these campy films. A few years ago I found one of these speakers at a flea market and it came home with me. After it sat in my garage for years, I finally decided it needed to be what ...

Johnny 6 is alive!

Designing a custom plate for the Arduino Robot, adding jumbo LEDs and displaying readings from an ultrasonic distance sensor to the LCD. My previous post on the Arduino Robot described how I took the Runaway Robot sketch and modified it work with the PING ultrasonic distance sensor. This post is still based around the same example sketch, however the code was not only further modified but additional compone ...

Controlling RGB LED using Arduino and Wi-Fi

In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi. In this RGB Flasher LED, we have used an Android Mobile App named “Blynk”. Blynk is a very compatible app with Arduino, ...

7 Segment Display Interfacing with Arduino

In this tutorial we are going to interface a seven segment display to ARDUINO UNO. The display counts from 0-9 and resets itself to zero. Before going further, let us first discuss about seven segment displays. A seven segment display got its name from the very fact that it got seven illuminating segments. Each of these segments has a LED (Light Emitting Diode), hence the lighting. The LEDs are so fabricate ...
