This project shows how information can be stored digitally as a series of 0s and 1s. The basic unit of a computer is a transistor, which can either let electricity pass or block it, just like a switch. The table in the corner shows what each transistor is doing. Zero means off, so no electricity passes. One means on, and the electricity is let through. There are three transistors. Click on them with the mouse to turn them on or off. How many colors can you make?
