a-ttiny-piano is a custom circuit plate can plays piano notes using an attiny85.
placa.1.mp4
- Basic knowledges about electronic circuits, soldier circuits and ironing method.
- Attiny85.
- Arduino UNO.
- Piezoeectric (or buzzer).
- 12 resistors 220 Ohms.
- Socket for attiny85.
- SMD switch.
- CR225 Lithium Cell 3V.
- Some SMD pins.
- Jumpers/wires.
- Protoboard.
To build this circuit you need to print the pianoV2_etch_copper_bottom.svg file inside printables folder on photo paper or propacolte paper for use the ironing method.
If you don't want use this technique, you can create your PCB using a PCB online service like PCBWay, just download the
attiny-gerber.zipfile.
You can program the attiny using your Arduino UNO in Arduino ISP mode.
Once you can send sketchs to your attiny, you need to send the piano.ino file.
