Recitation 1: Electronics & Soldering

At the beginning of each recitation, please carefully read through the all of the instructions. If you have any questions, please feel free to ask any professors, fellows, or learning assistants for help.

Materials:

    • 1 * Breadboard
    • 1 * LM7805 Voltage Regulator
    • 1 * Buzzer
    • 1 * Push-Button Switch
    • 1 * Arcade Button
    • 1 * 220 ohm Resistor
    • 1 * LED
    • 1 * 100 nF (0.1uF) Capacitor
    • 1 * 10K ohm Variable Resistor (Potentiometer)
    • 1 * 12 volt power supply
    • 1 * Barrel Jack
    • Jumper Cables (Hook-up Wires)
    • 1 * Multimeter

Recitation Exercise:

For this exercise, find a partner and work in pairs to complete the following steps.

  • Step 1: Build the circuits

With your partner, create three simple circuits on a breadboard based on the circuit diagrams below. When you’ve finished a circuit, take pictures or film the the finished circuit working. Record notes about the building process for each circuit, such as problems that you encountered, and how you fixed them.

Note: To help you read the schematics for the circuits, you may look at the components and their symbols at the bottom of this document, or refer to the diagrams in this reading.

 

  • Step 2: Switch the switches

Think about the circuits we are building, and their configuration. For instance, with a lamp or doorbell, the button or switch is never next to the actual light bulb or buzzer, but instead located in a place that is easy for the user to interact with. During the recitation, you and your partner will be brought to soldering stations learn how to solder. Here you will solder wires (50 cm long) to a larger push button.Once you have completed this, you should replace the push button switch in your circuit with the newly soldered arcade button for at least one of the circuits you built.

 

Circuit 1: Door Bell

Circuit 2: Lamp

Circuit 3: Dimmable Lamp

Documentation:

For your documentation, create a blog post and that includes the following information based on your experience in this recitation: Write down the list of components you used to build each circuit. Write down what these components are, what they do, and why they are included in this circuit. In addition, please include pictures and or videos of the completed circuit working, as well as a diagram of how the components are connected. Describe the process of building the circuit: Did the circuit work? Were there any moments where something failed? How did you solve the problem? Note what worked and what didn’t. Take time to reflect on this week’s readings and the recitation exercise. Publish your answers to the following questions along with your documentation.

Question 1:

After reading The Art of Interactive Design, do you think that the circuits you built today include interactivity? Please explain your answer.

Question 2:

How can Interaction Design and Physical Computing be used to create Interactive Art? You can reference Zack Lieberman’s video or any other artist that you know .
