g recu les 74hc14 hehehe
ou need the following parts to build the solarsoundmodule: 1 IC (typ 74HC14), 3 resistors, 3 capacitors, 1 solarmodul (2-3 Volt), 1 piezo-speaker. Pursue the construction plan. Start with the following values: resistors: 1 x 10K (10 Kilo ohm), 1 x 1 K, 1 x 100 Ohm. Capacitors: 3 x 10 µF. The sound variety of the modules is very wide, they can chirp, whistle, buzz or sweep. For a great variety of sounds and sound diversity you need to experiment for a while. You can use different 74HC14 types and change the values. Furthermore you can fit additional parts like diodes, resistors, potentiometer, piezos, solarcells, photodiodes or capacitors.
