Hello forum members
I'm working on arduino project and I need to make small and efficient power supply for the arduino microcontroller.
The only power source I have is 24VAC line, I would like to use that line to convert the AC to DC and then step down to 12V via regulator.
I'm adding the electric schematic that I made for the power supply.
I have few question to ask you because I'm still new to all this subject.
1. I need help to determine which fuse value should I put in the system - if my regulator output is 12V 1.5A (MAX) should i put 1.5A ? (The reason I'm putting a fuse is because if something went wrong I need it to burn the fuse instead of burning my home)
2. I need help to determine the value of the c2 and c3 in my system, I researched a lot on google and found few people that did similar projects and each one of them used different capacitor values, then I tried to look for how to calculate which cap value do i need and i didn't found something that would be clear and understandable enough for me.
3. If you see something wrong with my schematic it would be great if you could tell me about it, also suggestions for improvements are always welcome
Thank you very much for your help
