Week 11

This week’s assignment was about input devices. I think this was an interesting week because I have been reading about different Internet of Things modules for a smart home. I don't completely understand how to develop my own IoT circuit because I still need practice with programing a microprocessor.

The input device I decided to do was the temperature input device. I developed my own hello temperature board. I took Neil's schematic and followed his design in EagleCAD. I got a lot more familiar with the EagleCAD software because this week's topic starts to introduce many different components. I thought that it would be intersting to design my chip as a circle because I am tired of making the a square-shaped chip. The design process went smoothly, I was testing the different width setting for my traces. I know Neil has his recommended width settings, but it doesn't hurt to experiment.

The milling process this week was slightly stressful because my wafer board I was using for the Modella machine would sometimes lose it adhesiveness. This means that after waiting for the traces to be milled out the miill would slide through the chip when the tape took the chip off the platform. Unfortunate, but this is progress.

After the milling process, I compiled Neil's temperature board code onto my chip. I was having trouble with having a proper response from the .py source code. The temperature control would remain constant at 26.33 as the reading. My classmate Bill, compiled the code with his computer and after installing libraries the .py UI responded accordingly.
