Part 1) Breadboards
On a breadboard, you can create a circuit and test it without soldering. There are 2 rows of strips; one is power and the other is ground. All of the holes on each power and ground strip are connected. You can connect the power source to this and provide power to the components by wiring the power strip to the main strips. There are rows of strips with 5 holes on each row, and only those 5 holes are connected to each other. You can put the electronic components in the main strips to create the circuit.

Part 2) First Analog Circuits and Schematics
I tried to take out the switch and the potentiometer, and replace them with a push button and a photocell. However I ran into a problem where the photocell would affect both LEDs instead of just one. So I just kept the switch, and added a push button before one of the LEDs and replaced the potentiometer with a photocell. I thought if I covered up the photocell with my finger, the LED would turn off completely, but it didn't
Part 3) Multimeters
Multimeter is a measuring tool that can measure voltage, resistance, and current in a circuit. When testing a circuit, you can measure the voltage or the current at a certain point in a circuit. If you don't know the resistance of a component, you can easily measure its resistance before you connect it in a circuit. You can also test diodes and transistors.
Part 4) Final Project
Jun Hyung Kwon - 555 Stepped-Tone Generator
I really liked how he created a tone generator that produces sounds similar to the ones from Atari video games. It was interesting how he added the option to switch between a potentiometer and a photocell to control the oscillators, and the option to use a momentary switch, instead of it continuously producing sound. The sound was pretty neat when he demonstrated the tone generator with the momentary switch and the photocells.
Justin Schmidt - Reverb Spring Box
It was very interesting how he actually used a spring to make an analog reverb, which isn't as common nowadays. It was also interesting how he used a speaker and a piezoelectric pickup, which isn't how professional reverbs are made, but he came up with the design to make a reverb with what was available to him. The sound it produced reminded of the music from old black and white movies.
Nathaniel Picard-Busky - Onboard Effects Unit for the Electric Guitar
I liked how he went out of his way to make an onboard effects unit instead of an effects pedal. The placement of the sensor that controls the effects also shows that he considered the convenience for the player while designing the effects. The sound of tremolo was also quite pleasing and soothing except the clicking noise it made.
