For the project we had to build a number generator using a circuit board, LEDs, integrated circuits, resistors, capacitors, a button, a switch, and some batteries. We would learn how to solder doing this project.
1. The numbers were pretty evenly distributed they were around the perfect 16.67%. The Random Number Generator was quite fair, if I had more trials the results could have looked a bit more fair. 2. Admiral Grace Hopper was the person to coin the phrase debug. It was coined in Harvard University when Grace was working on the Mark II Computer. There was a moth stuck in a relay and started the term debugging.
The components we had to use in our project were integrated circuits, seven red LEDs, 7 180 ohm resistors, 1 1.2 k ohm resistor, 1 10 k ohm resistor, 1 100 micro farads capacitor, 1 .46 micro farads capacitor, 1 .01 micro farads capacitor, 1 push button, and 1 slider switch. This was the first time I was solder so there were problems. I made a solder bubble on my first attempt. After that it was fine when soldering. Several times I would have to suck up extra solder that I placed. I was difficult placing the integrated circuit in the holders. The pins are small and I was afraid of breaking them. When I first turned on my Random Number Generator only the middle LED was on. I looked to make sure that the integrated circuits in the right holders. I then had to resolder the contact points on the back of the circuit board. Some were flat and some bubbled. I reheated the bubbled ones and added solder to the flat ones. After that the circuit started showing random numbers correctly. This was a very fun project because it was hands on and we got to keep the finished project.
