Binary Counting using Arduino and LEDs

This repository is a quick example on how the binary system works. It shows numbers from 0-255 using 8 LEDs.

Required Parts

• 1 Arduino (With 8 outputs)
• 1 Breadboard
• 9 Wires
• 8 Resistors (220 Ω)

Structure

Code

When finished with the building, open the src/main.c file and simply copy 'n paste it into your Arduino IDE. Next, hit Ctrl+Shift+N in your Arduino IDE and copy the source code from include/types.h into that file, and save it as types.h. Now upload it to your Arduino and that's it - everything done!

Running on the Arduino

After you've uploaded your freshly compiled program, the 8 LEDs should light up sequentially (250ms delay) and stay on for half a second. Now the LEDs will be turned off and the program starts counting with the most significant bit on the left from 0 to 255 until you stop it (It counts from right to left). Have fun!
