The wheels on the bus...
For the communications project we worked collaborately to build several circuit boards which would communicate with eachother. I'm just going to outline very quickly since the regional starts in around six minutes. I made a circuit board, which looks like this, based of Craigs first outline. It was generally pretty similar to my previous motor boards with two exceptions.
First Exception
This one is simple. but as you can see here there are screw terminals. It might seem superflous and if so it's because it is. I do however need at least two since I'm using two motors (as soon as I can get a hold of the second one). The reason I had a third was because I had been planning to power it by battery but ended up adding a header anyways rendering the screw terminal for the battery unnecessary.
Second Exception
I used a crystal! Which I've never done before but according to Daniel it will be the best option for the connected boards. Other than that, so far, it's gone well. It was the first time ever I managed to make a board that doesn't have any 0 resistors! (except for the bridge) so that made me happy.
