11.INPUT DEVICES
Apr 13, 2016
This week's assignment is measuring something: add a sensor to a microcontroller board that you have designed and read it.
[Tool]
Software :Eagle (MacOSX) > Fabmodule (ubuntu)
CNC Milling machine : Roland MODELA MDX-20
11-1.Board design
For this assignment I choose a force sensor. And I used the data of temperature sensor as reference.Data > hello.temp.45.png
(I bought a force sensorr at 秋月(Akizuki).)


After that, I designed a board and save files as monochrome png data with 1000dpi.
png Data > input_150503_cut.png , input_150503_trace.png
Eagle Data > 160503.sch , 160503.brd
And Components that I used are as follows.
[Components]
- ATtiny45 x1
- 6 Pin SMD Type Male Headers
- 1uf Capacitor x1
- Attiny45 x1
- 3x2 Pinheads connector x1
- 10k Resistor x4
- Force sensor x1
11-2.Assemble
Next, I milled a board with CNC milling machine. I processed it in reference to the assignment of Week04.

11-3.Measuring 'something'
I used following Neil's program.Data > hello.temp.45.c / hello.temp.45.make
And I programed this code by using AVR.
