Starting to figure out how to wire everything up together and physically create the components of Heartree - i.e. scaling up from just 8cm jumper wire sensors, to 4m wires connected to a sensor. I wanted to investigate how the longer wires affects the capacitive sensing of the Arduino - would the extra length create more resistance, etc.
Interestingly enough, testing with 3 x 4m wires (one for the capacitive sensor, one for the light's power, one for the light's ground) didn't affect the sensing at all. The capacitive sensor on the test rope was just as responsive as before.
It was also my first time dealing with so much wire, and stripping wires with a proper wire stripper tool. Managed to buy a whole lot of equipment from Jaycar Electronics. Was also testing butt connector crimping techniques as a possible way to connect the brown hookup wires to the connections on the rope... but realised I didn't have the strength in my hand to crimp things properly. Will need to figure out another way to secure connections.
