This card adds a stack of LED’s to your CL-32. This will be a great way to try out some programing fundamentals.
The LED’s need to be cycled to be able to illuminate them all, so you will need to learn loops and toggling pins. You will also need to be able to chop up images and text into their individual pixels to be able to show them
Specs
The board is super simple. with 36 LED’s arranged in a 6×6 grid. The pins are as follows
- row 1 – pin 8
- row 2 – pin 15
- row 3 – pin 16
- row 4 – pin 17
- row 5 – pin 18
- row 6 – pin 21
- col 1 – pin 38
- col 2 – pin 39
- col 3 – pin 40
- col 4 – pin 41
- col 5 – pin 42
- col 6 – pin 47
The rows are connected to the positive side of the LED’s, and the columns are connected to the negative side, therefore setting a row high, and a column low, you will be able to light one of the LED’s.
If you do this quickly enough, and go through all the rows and columns as needed you can display images too 🙂
