COMPLEATED
It`s time to create a sensor board. I choose to create a light sensor. Here is traces, interior and components pngs:
Light sensor consist of:
- Microcontroller AtTiny45
- capacitor 1UF
- resistor of 10k Ω
- phototransistor
- resistor 49.9k Ω
- Headers
As many times before i used Modela to cut traces.
There was a problem with smd phototransistor, so i change it with phororesistor.
The soldered board looks like:
Next step is to program it. It`s necessery to have .c and .make file, like that you can find here:
http://academy.cba.mit.edu/classes/input_devices/index.html
To compile c file: sudo make -f hello.light.45.make
Fash using make: sudo make -f hello.light.45.make program-usbtiny
To start the LIGHT program: python hello.light.45.py /dev/tty.usbserial-(FTDI port)
