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 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.
Playing night rider with three 74HC595s
Connected three 74HC595s in series and entertained myself by simulating KITT from Knightrider. Would have hooked up the fourth one but was running out of realestate and LEDs. I should have a another breadboard in a few days along with some 7 segment leds that I will be hooking up and controlling with the 74HC595s.
