The Ones and Zeros of Computing

Things to do:

• Start with Switches, then call then bits.
• Single switch that changes a number from 1 to zero
• Single switch that turns a light on and off
• Two switches, two lights
• Seven switches to make an LED type number
• Transition to by showing how the one switch per segment for the nine numbers sucks compared to using binary bits and how many numbers you can make with that.
• Show black and white colors via switches.
• Show a black and white color picker that then sets the switches
• Show a RGB color picker.
• Show Letters ASCII
