Arduino #9 - Binary Counting

Hardware Layout for Binary Counting

Project uses a Shift Register

Count up from 0 to 255....then count down from 255 to 0 in binary - by flashing eight LEDs to represent your binary number. Follow the hardware and script in Boxall Project 16 (pp 116-121). We also introduce how to increase digital outputs with a shift register and make a spectacular visual lighting demo with binary counting.

After you finish the Boxall script (250 ms between blinking lights), speed up the timer. How fast can you go before you can't detect individual light flashing? A second requirement - you have to edit the program to count up (Boxall); then down.

Photo of your hardware
20-30 second video of counting up (only) - this is the Boxall sketch
30-40 second video of counting up (0 to 255) plus counting down (to 0; then repeat). You will have to write custom code to count up AND count down; you will also have to speed up the delay to capture counting up AND counting down in under 40 seconds
Google Doc with sketch that has custom code
Reflect on how many and what kind of debug errors you had (hardware, schematic, sketch/software, or reading/understanding the assignment)
