Solder FLORA circuit

We're going to extend the piezo wires and also attach a pull-down resistor.

Start with one piezo and trim the black wire a little shorter than the red wire. Slide on a piece of heat shrink tubing and strip the end of the wire.

Wrap the wire end around one of the resistor's leads (doesn't matter which one), and situate the two in the grasp of your third hand tool.

Strip one end on a piece of wire, and wrap this end around the same resistor lead. Solder the two wires to the resistor lead.

Once soldered, clip the resistor lead short and shield the junction with the heat shrink tubing you added earlier.

Now it's time for the other wire-- wrap the piezo's red wire and the other wire around the other side of the resistor, remembering to add a piece of heat shrink tubing before soldering.

Use a heat gun to shrink both pieces of heat shrink and repeat this process for the three other piezos.

Put the glove on and finesse the wires into a position that reduces strain and lets your hand move. Use painter's tape or masking tape to hold the wires in place as you route the ends towards the analog inputs on FLORA.

Solder each piezo's red wire (or whatever color your red wire became when you extended it) to a different analog input according to the circuit diagram.

Solder all the piezo's black wires to ground.

Before sewing FLORA to the glove, plug in via USB and test your rig using the code on the next page. You'd hate to have to unstitch anything if anything needs re-soldering!
