Story

Equipment needed * note that i substituted the sugru adhesive for velcro in order to reuse the board

For this project I used the circuit playground express board in order to make a customizable mood lamp. I started with a base platform of an Ikea lamp called sjopenna. After assembling the legs I proceeded to mount the board to the base of the lamp using velcro so that I would be able to re-use the board later on.

Mount the board with velcro

After mounting the board I proceeded to mount the toggle switch. I started by drilling a hole to fit the switch and then using the threading to screw mount the switch into the base.

Drilling the hole for the toggle switch.

After creating the toggle switch and screwing it into the base, I proceeded to wire the board to the toggle switch with the alligator clips.

Testing set up with li po battery

After making sure the setup was complete, I drilled another hole wide enough to fit the micro usb cable in order to adjust the code on the board while the project was complete. I used the drill bit similar to a router to create a rectangular hole.

Underside of base

once the battery was removed after testing the toggle switch and the usb cable was connected, I updated the code to achieve the brightest color combination that would yield the most functional results.

Final product

let value = pins.A3.analogRead()
pins.A1.setPull(PinPullMode.PullUp)
forever(function () {
    if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 0 && pins.A3.analogRead() <= 100)) {
        light.setAll(0x7f00ff)
        light.setBrightness(255)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 101 && pins.A3.analogRead() <= 200)) {
        light.setAll(0xff00ff)
        light.setBrightness(255)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 201 && pins.A3.analogRead() <= 300)) {
        light.setBrightness(255)
        light.setAll(0xff0080)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 301 && pins.A3.analogRead() <= 400)) {
        light.setAll(0xff0000)
        light.setBrightness(255)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 401 && pins.A3.analogRead() <= 500)) {
        light.setBrightness(255)
        light.setAll(0xff8000)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 501 && pins.A3.analogRead() <= 600)) {
        light.setAll(0xffff00)
        light.setBrightness(255)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 601 && pins.A3.analogRead() <= 700)) {
        light.setBrightness(255)
        light.setAll(0x00ff00)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 701 && pins.A3.analogRead() <= 800)) {
        light.setAll(0x00ffff)
        light.setBrightness(255)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 801 && pins.A3.analogRead() <= 900)) {
        light.setBrightness(255)
        light.setAll(0x007fff)
    } else if (!(pins.A1.digitalRead()) && (pins.A3.analogRead() >= 901 && pins.A3.analogRead() <= 2000)) {
        light.setAll(0x0000ff)
        light.setBrightness(255)
    } else {
        light.clear()
    }
})
