This is my NXT Bop-It! It has two buttons, one motor, the ultrasonic sensor, and the color sensor. I will go into further detail of each part in later steps. This robot was fun to make, but hard to progrogram, the reason for this is the fact that my software keeps acting up on me, for example, I try to click-and-drag, a block on the screen, and it freezes! So I apologize for no program.
