Week 11: output devices
COMPLEATED
After the week of input devices, came the week of output. I choose Speaker board, so here is the main parts of it:
To solder it you should have:
- Microcontroller AtTiny45
- Capacitor 1uF
- N-chanel transistor
- Resistor 10k
- 5V Voltage Regulator
- Headers
- Speaker
After milling and soldering it looks like:
Next step is to program it. I use my FabISP and .c, .make files, taken from:
http://academy.cba.mit.edu/classes/output_devices/index.html
As with my light sensor:
To compile c file: sudo make -f hello.speaker.45.make
Fash using make: sudo make -f hello.speaker.45.make program-usbtiny
As a result, i have a board, which playes simple programmed melody!!!
