Can anyone please, provide me a schematic on how to wire a 9v battery and a slide switch with 3 pins, with arduino nano 33 BLE, in a safe way?
I can't find enough instructions on internet and I am new to arduino.
Thank you!
I would not bother, the 9V batteries are not good for this type of application. I used google with your title and got a lot of hits explaining why and others on using a battery. If you post a schematic we will look at it for you. Good Luck.
