Introduction: Led Matrix IR Controlled With Arduino for Saint Valentines's
I did this heart with leds when I saw this instructable.
The main difference is that I've done as a matrix "7x6" although there are some holes in the matrix.
Step 1: Materials
All I needed was:
- 27 difused red leds.
- 2 prototyping boards.
- 1 plinth for ATMega328P
- Solderer and soldering tin.
- 1 paperboard box.
- IR remote control receiver and transmitter
And I start welding
Step 2: Leds
When I finished the matrix, I started with the basic box.
Step 3: Box
I used a milk box. Maybe it was so big.
Step 4: ATMega328P Internal Clock
After testing the matrix, I programmed the Arduino to use the microcontroller with its internal clock. Then I join the boards and I put the ATMega328P in the plinth.
Step 5: Voltage Input and IR Receiver
I used and USB cable to connect the ATMega328P to 5V.
Then I glued the plate to the box and wired the IR receiver.
Step 6: Finish
In the Arduino code there is the blink function which I implemented after recording the video.
I hope you like it.
Thanks you for watching!
