Infra Red Remote Controller Shield
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.
8×16 LED matrix controlled by 2 MAX7219’s
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.
UltraSonic Arduino How To – Parking your car with an Arduino
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.
MAX7219 and 8×8 LED Matrix on breadboard
I popped the MAX7219 and 8×8 LED Matrix from the kit and made it a little more social (watch video to see what I mean). Using the MAX7219 requires only 3 pins from the arduino, a couple capacitors and resistor. All the multiplexing is handled by the chip. When writing to the device you shift […]
MAX7219 8X8 Red Dot LED Matrix Kit
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 […]
Creating a Four Digit Display Using 74HC595 Shift Registers
My last experiment was with the three 74HC595s I was using to create the Knightrider effect on 24 leds. In this experiment I am going to add another 74HC595 and use all four to control four common-cathode seven-segment LED displays.
