Week_6 Assignments


Group assignment

As for the group assignment we learned how to use the oscilloscope to test the circuits and used arduino nano as a board to be tested. It was a great experience to see how the PWM (Pulse Width Modulation) works seeing how the signal width changes.
We also used the logic analyser to see the serial data and decode it and see the result.

Using the oscilloscope is quite easy all we did to get the PWM signal is that we connected the CH1 connector to pin number 9 in the Arduino nano and the ground probe to the ground in the Arduino. Then uploaded a simple sketch to the arduino to send PWM signal to pin 9.

this was my first time using the oscilloscope and I plan to use it in the PCB fabrication week.

As for the logic analyzer we used it to decode the serial data interpreted to "Hello World". By sending this string data through the Serial.println() function and connecting the logic analyzer channels ti the TX and RX pins.


Individual assignment

Like I said I used KiCAD to design the circiut I wanted to make a circiut that helps to connect the Xiao ESP 32 C3 to the prepherals whatever the protocol is whether it is I2C, SPI or UART.
I learned KiCAD following the documentation and the "Getting Started With KiCAD"tutorial provided by KiCAD.

KiCAD has a fixed workflow (I think ^^):
**I found that it is more efficient to run through these steps after adding each component.
