Now first things first, I don’t recommend making your own 8×8 LED matrix out of individual LED’s (because it is very time consuming!) I do recommend purchasing yourself one (or more) of the 8×8 Bi-colour LED matrix displays off ebay. they are incredibly cheap and are very easy to use. I buy mine from sure …

  I was having a bit of a think about what to do with the sixth installment of this course. So what better than to add a keypad so that we can control what is displayed on the seven segment display. What you can expect to learn: How to interface a keypad to the microcontroller …

Seven segment displays are extremely useful devices. We can quite easily drive one, two, three or more seven segment displays with just one microcontroller – we will start with just one so you can see how the circuit and code works, then we will build on that to get to four seven segment displays running …

We’ll so far we have been using the microcontroller to make some nice LED’s flash and do pretty things. But what about using a couple of pins as inputs? That’s exactly what we will be covering in this module. This circuit has a left push-button and a right push-button. You press the left button to …
