Week 13 - Input devices

by Javier Hernández


Assignment

Measure something: add a sensor to a microcontroller board that you have designed and read it.


The idea

For the assignment of this week I will manufacture and program a step response touchpad board, I am taking as a guide the ssignment made by Arnau Tasias, taking advantage of the experiences that he had during the accomplishment of this exercise.

For this exercise we need 2 boards, one to receive the information (input board)and another to send it (touch pad) conected by a 2x2 header pin

The boards

First step is to redraw arnau's boards, "Step" and "Stripe"

Step Board

Components

1 x Capacitor 1uf

2 x Resistor 1 Mohm

1 x Resistor 10 k

7 x Resistor 0

2 x Pin head 2X2 SMD

1 x Attiny45SI

1 x Avrispsmd 2X3 SMD

1 x FTDI SMD Header 1X6 SMD

This is the result of the redrawing of "step" board

Stripe Board

Components

1 x Avrispsmd 2X3 SMD

This is the result of the redrawing of "stripe" board. I made a modification on the png to adjust it to the board i have for the milling

After milling this is the result. I didnt make the outline process because i get out off tools just at the end of the traces process, i broke the tool!

To know how to perform the milling chack the information of the week 4 Electronic production

Programming
