Arduino: Rock, Paper, Scissors |
After learning about the basics of electronics we then moved on to some more physical experiments. For theses experiments we used a breadboard in able to organize our wires and make a circuit without holding all the wires together with our fingers. A picture of a breadboard is shown at left. We were then assigned several experiments to conduct with different electronic components such as timers, LEDs, timers, resistors, capacitors, etc. It was at this point where we were told to figure it out on our own. The whole idea of this lab was to prove an idea or statement that was given to us through building it and seeing if it worked. If it did, we would go on to measure and record our results. If not well we probably set the circuit up wrong. Once we had done all the experiments, we had to put our skills to the test and complete the blinky light quiz. For this we were given a circuit diagram we then had to recreate the circuit it was described as. Now this may sound self explanatory, but when you have several different components and over 12 wires things start to look the same. However we did it after the 3rd try and we realized that two of our wires were touching which messed up the whole circuit. Throughout these experiments we had several mini lessons scattered in such as what Ohm's law and Kirchhoff's law is. Ohm's law is that voltage is equal to the current times the resistance. Kirchhoff's law, which has two parts, first is that the current law. This is stating that the amount of current going into a circuit is the same as the amount of current coming out of it. Second there's the voltage law. This is stating that the sum of all the voltages around a circuit must be 0. All three of these laws are true and have been proven through our experiments.
