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!

Did you use the ATMega328P alone?

Yes, only the ATMega328P. First, you have to configure it to enable the 8MHz internal clock instead of 16MHz clock, which is in the Arduino Board.

Very good and nice. Can u add the step how to make it by vidoes

Thank you. I'm so sorry but I don't have videos about the soldering process.
