In lab 2 we got to become a little more familiar with breadboards, multimeters, and other various components associated with breadboards. The first step of the lab was to simply make sure that our wonderful instructors set us up with all of the parts we needed for the lab. The next step was to make sure that our multimeter was working properly by touching the two probes together to test for continuity.
We decided to try out the arduino 5V power supply this time instead of the power jack we constructed in the last lab just so we could become more familiar with how the arduino worked (because we're guessing we might end up using it later on). We used our multimeter to test various things including the small switch that we were provided. We also used our multimeter on different resistors that we were provided. We learned how to set up the multimeter when trying to detect for a particular resistance (in ohms) by setting it to the same range of resistance we wanted but slightly higher. We then installed a 5V voltage regulator to keep the voltage constant.
Next we installed an LED and the switch. This was our first trial in which we discovered that our button was not installed correctly as you can see the light is on when the button is not pressed and it turned off once the button was pressed. This could have been fixed by rotating our switch either clockwise or counter-clockwise.
Lastly we changed out the button switch for the potentiometer you see below. Using three alligator clips we were able to connect the potentiometer to some pins eliminating the need for solder. The only issue we had was that turning the potentiometer only half of a rotation cut the LED completely off.
