This kit contains the electronics parts and the circuit to build a sound generator module with 16 different voices. It is widely used in door bells, scale modelling, toys, or alarm systems, and it is very easy to build and to use.
The 16 different sounds can be selected by the 4 switches, or by supplying logic levels to the 4 pins ABCD.
Operating voltage: 4.5 – 5V Dimension: 48 x 41 x 12mm Time to build: 15 min. Difficulty level: easy
All parts and their values are printed on the PCB, the connection of the sound chip itself can be seen in the pictures. Means, it is no rocket science at all, to build this kit.
The power supply must be hooked up to the header marked with [+] and [-].
