Good morning everyone, is there anyone among you who can help me design the circuit, I’m not an expert, I ask for your help, I have space problems, I was thinking of using seeeduino xiao samd 21, input power supply a fully charged 4S 16.7v battery pack, two buttons (PIEZO) and two independent outputs, the first button only does on/off (on a mosfet output 1),
the second button works in pwm on output 2
- 1st pulse turns on a mosfet and emits 12v (200w) and sounds a buzzer once
- 2nd pulse passes the mosfet output and 11v (200w) and sounds 2 times
- 3rd pulse sounds 3 times and turns off this output (output 2)
I would also insert an ADC charge control under a threshold to be decided long sound and turns everything off
since this goes inside a battery pack I would like it to go when not in use in deep sleep for console the little ones
Do you think it’s complicated? Can you help me? Is there anyone who wants to give me a hand
Thank you
