6. Electronics Design

This week I worked on Electronics Design and it was a scary thought as I felt that I didn’t understand a single word during the lecture, although I have an electrical power engineering bachelors. Anyway I am glad as I feel that some where in my brain things are coming back to life.

Group Assignment

We met with the Onik and Maxime to do the group assignment and I was left with investigating the behavior of a micro-controller XIAO RP2040.

After trying to use a multimeter that is brand new yet not functional, we agreed to make our own to measure an unknown resistance

I used an example from the basics in the Arduino IDE after downloading the software with the guidance of for Digital Read Serial to adjust and use for my own XIAO RP2040

In here I used this equation from Wikipedia

Then used my own numbers to get the results. I used 1k ohm resistance to measure 330 ohms (the unknown resistance)

This is the physical circuit which wasn’t actually working as the pin on the breadboard that I have used was not working most probably.

While this was the circuit that got us the right readings

Then I wanted to learn how to use KiCad and I tried to the same circuit on the software

I added the FabLab library following these steps

I used these attributes for my PCB design

And this is the design for the circuit that we have used for the assignment

Individual Assignment

I went to chatgpt to see how I could design a PCB for sending and receiving and I used this prompt

I managed after asking for images from chatgpt so I could understand how I should do the work and I was able to find the components
