Tilt Sensing Bracelet

Step 4 Soldering

Cut a piece of perfboard 8 x 10 holes big. With the conductive strips running the longer length. File the edges. Bend the legs of your eight female headers if you dont have any ready bent ones. Solder them to one of the ends of the perfboard. This is going to be a series of pull-up resistors going from each input to the ground.

Solder the 10 or 20K resistors to the board as shown in illustration. The red line represents the VCC and the outer line where all the resistors accumulate represents the GND. The rest are your six digital inputs.
Clip the ends of your wires. I like to use a nail clipper.

Solder the ribbon cable to a row of 8 male headers. This will plug into the bracelet. On the other end, make sure to separate the VCC and GND wires and solder these to two connected male headers. These will connect to the 5V and GND of the Arduino. Solder the rest of the wires to a row of six male headers. These will go into your analog or digital inputs, depending on your code. I chose to plug them into my analog inputs because I already had the code for reading them running on my board. But it wouldnt take more than 5 minutes to change them to digital.
