Here is a shield for Arduino that makes adding quality sound to your products easy. It can play up to 22KHz, 12bit uncompressed audio files of any length.
The LCD Button Shield from Sparkfun Electronics provides a 16×2 LCD screens along with a keypad consisting of 5 keys — select, up, right, down and left. With this shield you will be able to move through menus and make selections straight from one board attached to your Arduino without requiring a massive tower of shields.
Made use of The Forge makerspace at North Branch library to construct my first Arduino Shield. This shield adds 7 Status LEDs, an Infra Red LED, an Infra Red Receiver and a piezo buzzer.
Expanding on my experiment with the MAX7219 controlling an 8×8 LED Matrix I added a second one. Both of the 8×8 displays and controllers were part of kits that couldn’t fit neatly side by side, but the concept can still be demonstrated.
Using a Maxbotix Range Finder, Kevin Dahhar show you how to make a circuit that helps you back your car up into the garage, and put the Arduino into a super low power sleep when the circuit is not needed.
After reading up on Project #21: Creating an LED Matrix in The Arduino Workshop I set out to find a 8×8 common cathode led matrix. I saw this MAX7219 8X8 Red Dot LED Matrix on Amazon and while I was looking to experiment with using two 74HC595’s to control the rows and columns of the 8×8 […]
