Design of a simple electronic keyboard [Copy link]

I have seen some electronic keyboard materials posted online, but I don't know the scales, and I don't know how to press a key to make a sound. I need a simple electronic keyboard design, the simplest one. Is there anyone who can do it? I just need to be able to make 1, 2, 3, 4, 5, 6, 7.

Look up the correspondence table between syllables and frequencies, and then use two timers to make music!!!  Details Published on 2014-6-20 15:45

First, you need to know the relationship between pitch and frequency. You can look it up. If you can't find it, I'll send it to you. Second, make a circuit that can emit a certain frequency. Then let this button control its frequency. This circuit can be an analog circuit or a single-chip circuit. If you don't know anything about single-chip microcomputers, it is recommended to use an analog circuit.

Baidu searched the relationship between musical scale and frequency, and found a lot of them. Then use the timer of the microcontroller to generate a signal of the corresponding frequency.
