Analog 3 is the GSR (Galvanic Skin Response) sensor.The two contacts are conductive metal. Normally two fingertips are used to keep touch with the contacts.I placed two copper contacts like so, in spots my index and middle fingertips naturally...
Analog 4 is the Temperature sensor input.The TMP36 outputs an analog voltage that represents the temperature.A simple formula gives the temperature based on voltage:float celsius = ((voltage * 1000) - 500) / 10;
Analog 5 is the ambient light sensor. It outputs an analog voltage that is proportional to the amount of light it is exposed to.I mounted it inside the glasses frame.
Before starting the whc-switch service, you should add some components. You need a simple switch, a blue led, a red led and some resistors to match your led voltage.It is as simple as it looks like. After everything has been connected , you can start...
Now you can start building your device using the materials you choosed. If, like us, you could only get stereo jacks but you want to use them as mono, you can refer to this picture for how to solder it:Mono versionStereo versionWe can't get you so much...
Connect driver boards with ribbon cables. 7-segment display boards and led board uses 10 wire cable, 14-segment displays use 12 wire cables.Note that there is no 12 wire IDC plug, so I used 14 wire plug and left the last two wires unconnected on the...
