7 Segment LED Display (use Interrupts) 1. About the lab: Display 0-9 digits on 7 Segment Display using Arduino. The number counts down from 9 to 0 For example: 9,8,7,6,5,4,3,2,1,0,9,8,7,6,5,4,3,2,1,0,9... Different from Labl, you are not allowed to use "delay()" function. You must use interrupts to achieve "delay". 2. What do you need: . Arduino Uno 3 7 Seven Segment Display (Figure 1) 3 x 220 Ohm Resistors Jumper Wires 1 Pushbutton A IL F m G E U D (DP) 3.
