1. Resistance Measurement

2. ProbleM Measure four resistance values for each straw in a pallet
Inside-Inside
Outside-Outside
Inside-Outside
Outside-Inside
How can this process be automated?
Measuring by hand takes ~45 minutes per pallet
Plan to design PCB (printed circuit board) to use with an Arduino unit for logic I O

3. Straw Contacts I O I O I O I O
Copper Tape

4. Circuit Design
Demultiplexer  Inverter  Quad Bilateral Switch (Input from straws, outputs tied
together to DMM
Currently testing design to implement on a few straws before designing PCB
