    How can you design a PCB for climate control as well as to turn on lights via relay?

    I’m pretty much a noob when it comes to hardware and for awhile I have been trying to figure out how to design a PCB layout. The Problem I have is trying to figure out the values for capacitors and resistors how to connect them with the other parts (like pull up resistor, bypass capacitor etc...
