Sketch
Sketch
use TinkerCad to construct and simulate the circuit
draw (pencil) a circuit in your design notebook that shows each element
seek approval from teacher
Construct Circuit
Construct Circuit
gather materials listed above
layout your circuit on table
connect your circuit by twisting wires lightly (you will need to undo them later)
Testing
Testing
Add two (2) AA batteries to the battery pack
Test the circuit by pressing the button, does the LED light up?
Does the light flicker or stay on consistently?
How do we troubleshoot (debug) the circuit?
Troubleshooting
Troubleshooting
Did you press the button?
Are there batteries in the pack?
Are all connections secure
Are the LED leads touching (short circuit)?
Can you isolate the problem area(s)?
Assemble the Bottle
Assemble the Bottle
Once the circuit is working reliably, determine a way to get the battery pack in the bottle. How might you fit it in there?
Use the PDF file above to setup the LED and button in the cap
