7. Electronics design¶

This week I had to build attiny 1616 and then program the hello echo code into it.

Group Project¶

For the group project for this week to learn how to use oscillascope and the multimeters. Both are used to check for errors on your electronic boards. They both can be used to check voltage and pin connections, the oscillascope is more specific because it has a graph visual that can help you pinpoint where the problems are. We also had to learn how to program an LED to work when a button is pressed using a breadboard. Osillascope Multimeter Bread Board

Designing¶

Designing the board was hard but fun. It was hard to get all the different wires to connect to different points without crossing them. Design

Milling¶

Milling the board was a challege because I didn’t realize how long my board was at first so the mill just kept on going off the copper also my boaed was very wide so ended up having to use a brand new copper sheet but it worked out well in the end. Milling

Soldering¶

Soldering went better than last time because I’ve had more practice with it. the 1616 micro processer was a challenge to get on because the pads were small and the chip has twenty legs. A lot of the pins ended up getting stuck together at diffrent points It seemed like whenever I would unstick a couple of pins two more would get stuck together. Brandon ended up helping me remove some of the solder and discovered that some of my treds were connected to two pads instead of just one, so He ended up up using a dremel and the 1/64 drill bit to seperate one of the pads from the traces. But other than that it went really well and I stuck everthing on the right way.

Programming and getting it to Work¶

Programming was hard because of the above reasons, but once the traces were fixed it worked. It Works
