I am using wires and I know where they go for the second gate but I don't know where to connect them for the first gate (where the input of the second gate would be coming from).
I'm creating a half-adder with transistors (no chips), switches, resistors, and jumper wires. To make the XOR gate I am connecting OR, NAND, and AND gates together. Individually I can make each of them and light an LED etc. but I don't know how to connect these gates between each other.
