Circuit Board

Plan

I progressed from TinkerCad > protoboard > Autodesk Eagle > milled board to learn about manufacting a circuit.

TinkerCad (breadboard)

Analysis

Using TinkerCad, I was able to practice different with different circuit components. In the pictures above, I experimented with a slide switch, photoresistor, button switch, and potentiometer. (Every circuit is connected to a 9V battery and powers an LED.)

Breadboard

• (TinkerCad circuit is basically a digital breadboard)
• helps to plan a circuit
• not permanent, so you can move the components around and try out different arrangements

Work Flow

1. Open TinkerCad and log in.
2. Go to the circuits section.
3. Create a new circuit.
4. Name the circuit.
5. Choose a breadboard (small or large).
6. Attach a 9v battery (may change based on what you are powering.
7. Layout your components.
8. Connect with wires.

Protoboard

Analysis

After I planned my circuit in TinkerCad, I built the circuit on a protoboard. My protoboard was a little messy, because this was the first time I had purposly made solder bridges

Protoboard

• the step between a breadboard circuit and a custom printed circuit
• made from a flat sheet of resin with a grid of holes drilled in them and conductive copper on the underside
• components connected with solder bridges

Work Flow

1. Choose a protoboard.
2. Find the correlating components from the TinkerCad circuit.
3. Lay the circuit out exactly like the TinkerCad design.
4. Connect wires between components.
5. Connect wires to components with solder bridges.
6. Attatch battery to circuit.
7. Turn battery on!

Autodesk Eagle

Analysis

Using the program Autodesk Eagle, I mapped out the circuit diagram. Eventually, I will mill the design out using the Othermill.
