If you have seen my other instructable on ram memory, you probably know that I used transistors to make a register. In this instructable I will show you how to make a register using CMOS gates.

Step 1: What is CMOS?
Step 2: Why use CMOS?
Step 3: What You Will Need
***These are per-bit numbers***
8 2N7000 Small signal n-channel mosfet
8 BS250 Small signal p-channel mosfet
2 Pushbutton switches
2 10K ohm resistors
1 1K ohm resistor (or whatever value is needed for your LED)
***These are necessary no matter how many bits you make***
pliers (not necessary, but very very close)
