This DIY keyboard / piano module is an ideal learning project for beginners in the field of electronics soldering. It is also a fun project for anyone who enjoys tinkering with electronics.
Overview:
- Easy to solder
- Supply voltage: 3V - 12V direct current. A small battery or a 9V block is therefore already suitable
- Very motivating due to the expected result - your own little musical instrument
- 8 different musical tones
- The positions for the individual components are marked on the circuit board
