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.

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

When I finished the matrix, I started with the basic box.

I used a milk box. Maybe it was so big.

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.

I used and USB cable to connect the ATMega328P to 5V.

Then I glued the plate to the box and wired the IR receiver.

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!
