Step 3: Approach 1: Digitized Sensor Output - Simplest way
1. Using a #62 drill bit drill a hole through the circuit board from the copper side at
the locations marked Sd and Jmp1 in the photo. The locations are indicated
by a yellow dot. Both locations have a convenient little circular pad that
we can use. If you can not find a #62 drill bit, see if your hardware store
carries a #60, this will work. A drill bit especially made for PCB drilling
works the best.
2. Cut the trace that is next to Jmp 1. You might have to click the "i" at the corner
of the photo to see the location clearly.
3. Place a wire jumper on the non-copper side of the PCB between Sd and
Jmp1 and solder.
4. Remove the switch from the black female connector's wires. The black
male connector now has the conditioned digital sensor signal and ground.
