You read that right.
Several days ago, me and my friends were working on an Arduino project for a certain subject—Human and Computer Interaction to be precise. Fortunately, we weren’t doing this at 2 o’clock in the morning; instead, we were doing this project at around 5 p.m.
Even to convince my friends was hard work. I had to buy several rather expensive components, then storm through the heavy rain. I couldn’t just join my friends; well, I had this assignment that needed to take care of first.
Eventually, I joined and bought both of my friends some snacks. Fortunately, this time it wasn’t raining. After done with the assignment, I stayed for a while—until maybe 9 p.m.—and went home when I exactly had to pee; there was no water there (My friend said it was not unusual). We enjoyed our times, I hope.
Anyway, here are the main components and parts used in this assignment:
- Arduino Uno (and its’ cable)
- Jumper cables (you’ll know how many)
- 4 7-segment common cathode
- Breadboard (the big ones, but suit yourself)
- Keypad 4 x 4
- IC 7400 and IC 7404 (I presume it’s NAND and NOT Gate)
And here are the pictures:
