Wiring
Slide Switch Wires
Prepare a set of two wires about 3 inches (7cm) in length.
Using wire strippers, remove a bit of insulation from the tips of each wire.
Tin the exposed wire by applying a bit of solder to them.
Snip off one of the leads on the slide switch, either the far left or right but not the middle. Then trim the two remaining leads short, about half their length.
Solder Wires
Solder the two wires to each of the leads on the slide switch.
A pair of helping hands can assist while soldering wires in place.
Solder the two wires from the slide to the EN and GND pins on the top of the Feather.
Hall Effect Sensor Prep
Prepare a set of three multi-colored wires (red, blue and white) about 5 inches (12cm) in length.
Trim the legs short from the 10K resistor and hall effect sensor.
A piece of heat-shrink tubing can help keep the wires bundled together.
Solder Hall Effect Sensor to Feather
With sensor facing up, solder Pin 1 to the red wire and a leg of the 10K resistor.
Solder the blue wire to Pin 2 of the hall effect sensor.
Solder white wire to Pin 3 and the other leg of the 10K resistor.
With Feather facing down, solder red wire to 5V pin, blue wire to GND pin and white to Servo pin.
Wires from NeoPixel Stick
Prepare a set of three wires about 3.5 inches (8cm) in length.
Solder the three wires to the GND, DIN and 5VDC pads on the back of the NeoPixel stick.
Shared Ground Wires
Prepare ground wires for sharing across the slide potentiometer, key switch and toggle switch.
- Short wire: 1 inch (2.5cm)
- Medium Wire: 2 inches (5m)
- Long Wire: 4.5 inches (11.5cm)
Panel Mount Controls
Get the three input controls ready to panel mount to the front half of the enclosure.
Remove the hardware from the toggle switch.
Insert the toggle switch through the appropriately sized hole.
Use the hex nut to secure the toggle switch to the enclosure.
Panel Mount Slider
Place the slide potentiometer onto the front half of the enclosure with the nub fitting through the slit.
While holding slide potentiometer, turn the enclosure over, line up the two mounting holes.
Insert and fasten two M2 x 8mm long machine screws to secure the slide potentiometer to the enclosure.
Mount Key Switch
Orient the choc key switch and press fit it into the square cutout on the front half of the enclosure.
Solder Ground Wires
Start with soldering the medium ground wire to the toggle switch.
Solder the other end of the medium wire and the short wire to Pin 3 on the slide potentiometer.
Solder the other end of the short wire and the long wire to either pin on the choc key switch.
Input Control Signal Wires
Prepare three multi-color wires (white, green, yellow and red) about 4.5 inches (11.5cm) for the input controls.
Solder Wires to Slide Pot
Solder the red wire to pin 1 on the slide pot.
Solder the yellow wire to pin 2 on the slide pot.
Solder Wire to Toggle
Solder the white wire to the either far left or right pin on the toggle switch.
Soldered Wires
Take a moment to check all of the wires have been properly soldered to the various pins.
Adding a piece of heat-shrink tubing can help keep the various wires bundled together.
Solder Wires to Feather
Solder the green wire (choc key switch) to pin 5.
Solder the red wire (VCC on slide pot) to one of the 3.3V pins.
Solder the yellow wire (wiper on slide pot) to the A0 pin.
Secure Toggle Switch Wire
Insert the white wire from the toggle switch to the Btn labeled pin on the Feathers screw block terminal.
Use a flat head screwdriver to secure the wire to the screw block terminal.
Secure Ground Wires to Feather
Locate the ground wire from the NeoPixel stick and the remaining ground wire from the choc key switch and insert them both into the ground labeled pin on the Feathers screw block terminal.
Use a flat head screwdriver to secure the two ground wires to the screw block terminal.
Secure NeoPixel Wires
Insert the VCC wire from the NeoPixel stick to the 5V labeled pin on the Feather screw block terminal.
Insert the DIN wire from the NeoPixel stick to the Neo labeled pin on the Feather screw block terminal.
Use a flat head screwdriver to secure the two ground wires to the screw block terminal.
Prep Speaker Wires
Shorten the socket picoBlade molex cable so its about 2.5 inches (6.3cm) in length.
Using wire strippers, expose about 0.12in (3mm) of each wire.
Connect it to the speakers plug cable.
Secure Speaker Wire to Feather
Insert the wires from the speaker to the audio pins on the Feather screw block terminal (red wire to positive, black wire to negative).
Use the screwdriver to secure the wires to the screwblock terminal.
