9. Input devices

Group Assignement

This week I learned how to test, read and integrate input devices into my PCBs.
Some of of my learnings:

• Again, make sure footprintes, schematics and connections are done correctly if a new PCB will be created.
• Creating PCBs with the vinil cutter and copper tape can make the iteration process SO flexible.
• Also using acrilic made it very simple to iterate and adapt along the way.
• Testing every connection is key
• Sensors may need some calibration

My process for this week's assignement was a little improvised and chaotic but it turned out great (and it was really fun)

1. First I started designing a brand new PCB from scratch because I though I had 2 microcontrolers (one used for ñast last week's assignement, another one left)...

2. Turned out I lost or didn't get the second microcontroler, so I decided to reuse last week's PCB and see if I could just add the sensor.

3. I analyzed my micronphone sensor, measured, played around with orientation and sketched some paths with marker over the acrilic. It all looked good in theory XD I just had to use the other phase of the acrilic, creating my own DIY inter-phase paths.

4. Made the holes I needed to connect the 3 pins of my microphone sensor: OUT, GND and V. Thinking it shouldn't be too complicated, fully trusting my soldering skills and my vision.

5. Added some single pins and copper tape from last week's spare cut manually to create my tracks. (Crossing my fingers with every move)

6. Tested every connection and made any necessary adjustments

7. Secured and covered all important (or loose) connections with silicone to get the final PCB

8. Uploaded a new Code to the microcontroler

9. Tested and calibrated the sensor

10. Got my hacked pcb working :D

I'm so happy and proud I made this work.
