13.- Input Devices

Apr 26

Assignments:
-measure something: add a sensor to a microcontroller board that you have designed and read it

- Choice
- Attempt
- Doubts
- Final

For the week of input devices hesitated between a 100k thermistor or Inductive Proximity Sensor because both are used in 3d printers.

I have decided on the thermistor because I would like to implement it in a PID system.

datasheet thermistor 100k

I took as a reference Niel board. Changing the resistances that go to the imput pins from 10k to 100k

Here are my schematic and my board

I modify the PNG with gimp

I was confused when in an adafruid tutorial they only used a single pin to measure the thermistor adafruid

I try to program but it can not burn the bootloader. That's why I made another board simpler. And I managed to programm this

This week in my attempts failed and I decided to create a replicate of Neil's thermistor exercise. This last board is for 10k thermistor.
Also in my final project try again with better results.
