What it does

A computer that takes in punch cards and does

How I built it

The core is an Arduino, which controls the sensors and motors. The card reading is done using 4 IR sensors. The cards are fed in with a motor, and the output is shown on an LCD screen.

Challenges I ran into

  • Wiring the LCD
  • synchronizing the the reading of the card with the motor's movement/feeding of the card,
  • mounting everything cleanly
  • coupling the motor
