Only downside is that you need to keep the switch turned on to hear the melody.
Other thing that can be done is to charge a capacitor when someone presses a push button switch and then as the cap discharges the melody keeps on hapenning.
What do you say?
Good one brother, I am going to use your logic along with few other components to create my own PCP
Thanks again
Can you describe how to input the melody to the ic um66?
There is no input. It's is already stored on the IC
Please I Want tone of bird 🐦 is there .
I don't think there's a dedicated IC available capable of generating bird sounds.
You could probably do this with an Arduino+SD card+audio amplifier.
@@ElectroGuruji I've more like this i.c and same tone but i have project for bell 🔔 door electronic want tone off bride sound . thank you
That bell looks a lot like a speaker
The speaker converts the electronic signal into an Audio signal
