it’s been great fun studying all the projects in this edukit, but I want to take things one step further with the buzzer. I want to make a circuit which switches between feeding the buzzer with a high current and feeding it with a low current. Basically, I want it to alternate between buzzing loudly and buzzing less loudly. Is this possible with the components included in this kit, or do I have to get some kind of IC?
I’ve tried hooking the buzzer into the astable multivibrator, but from the result I guess that wasn’t a very clever idea (I think I bypassed the transistors by doing it and the buzzer made no sound if I recall correctly).
I still have a long way to go before I fully understand the basics about how all the components work and how they should be used together. Sorry if this is the wrong place for this kind of question.
