Space Ghost Glove
Intro: Space Ghost Glove
STEP 1: Ingredients
You'll need the following:
Arduino board (I used an Uno during prototyping but would probably go with a Lilypad, Micro, etc.)
LED strips (Neopixel strips would be cool too but I used standard strips so they'd all light at once)
Pull-up button
Wire
Battery
Battery harness
Glove
Soldering iron and wire
Wire strippers
STEP 2: Wiring It Up
The most difficult part of this build is the soldering. The LED strips require a delicate touch. I recommend you apply some solder to the contact pads first and then solder the wires to the pads. It's probably a good idea to try to protect these confections, maybe use electrical tape or hot glue. I didn't make mine as a long term project so I didn't do this.
The strips I used are common anode but it was easier for me to wire them up backwards and reverse the code. In other words to light the strips I used digitalWrite LOW. To turn them off use digitalWrite HIGH. this also means that we use analogWrite 0 to make each color full brightness. (at least I think this is why I had to change the programming haha)
After you solder the strips you should solder the R, G, B, and + wires together in groups (all the Rs, etc). Now you can connect them to the Arduino.
Connect + to the + of the battery. The - of the battery to ground. Or if you will run the Arduino off the same battery then spice the + from the battery harness so you can run one lead to the lights and plug the other end in.
Connect Green to Pin 6 or suitable PWM pin.
Connect Red to Pin 5 or suitable PWM pin.
Connect Blue to Pin 3 or suitable PWM pin.
Connect one side of the button to one of the GND pins and the other to Pin 2
My strips are also 12v so I used a 9v battery, it also powers the Arduino.
STEP 3: Programming
I borrowed code from Adafruit (https://learn.adafruit.com/rgb-led-strips/example-... and (https://github.com/adafruit/Adafruit_NeoPixel/tree... and mashed them together. I made a few changes and this is the result:
// color swirl! connect an RGB LED to the PWM pins as indicated
// in the #defines
// public domain, enjoy!
#define REDPIN 5
#define GREENPIN 6
#define BLUEPIN 3
#define BUTTON_PIN 2
#define FADESPEED 5 // make this higher to slow down
bool oldState = HIGH;
int showType = 0;
int r = 255;
int g = 255;
int b = 255;
int f = 0; // counter for flashing lights
void setup() {
pinMode(REDPIN, OUTPUT);
pinMode(GREENPIN, OUTPUT);
pinMode(BLUEPIN, OUTPUT);
pinMode(BUTTON_PIN, INPUT_PULLUP);
}
void loop() {
bool newState = digitalRead(BUTTON_PIN);
// Check if state changed from high to low (button press).
if (newState == LOW && oldState == HIGH) {
// Short delay to debounce button.
delay(20);
// Check if button is still low after debounce.
newState = digitalRead(BUTTON_PIN);
if (newState == LOW) {
showType++;
if (showType > 4)
showType=0;
startShow(showType);
}
}
oldState = newState;
}
void startShow(int i) {
switch(i){
case 0: digitalWrite (REDPIN, HIGH); // Black/off
digitalWrite (BLUEPIN, HIGH);
digitalWrite (GREENPIN, HIGH);
delay(500);
for (f = 0; f < 4; r++) {
digitalWrite (REDPIN, LOW); // White - blink 3 times
digitalWrite (BLUEPIN, LOW);
digitalWrite (GREENPIN, LOW);
delay(200);
digitalWrite (REDPIN, HIGH); // Black/off
digitalWrite (BLUEPIN, HIGH);
digitalWrite (GREENPIN, HIGH);
delay(500);
}
break;
case 1: digitalWrite (REDPIN, LOW); // White fade to red
digitalWrite (BLUEPIN, LOW);
digitalWrite (GREENPIN, LOW);
delay(500);
analogWrite (REDPIN, 255); // Red
delay(2000);
digitalWrite (REDPIN, HIGH); // Black/off
digitalWrite (BLUEPIN, HIGH);
digitalWrite (GREENPIN, HIGH);
break;
case 2: digitalWrite (REDPIN, LOW); // White to green
digitalWrite (BLUEPIN, LOW);
digitalWrite (GREENPIN, LOW);
delay(500);
analogWrite (GREENPIN, 255); // Green
delay(2000);
digitalWrite (REDPIN, HIGH); // Black/off
digitalWrite (BLUEPIN, HIGH);
digitalWrite (GREENPIN, HIGH);
break;
case 3: digitalWrite (REDPIN, LOW); // White to blue
digitalWrite (BLUEPIN, LOW);
digitalWrite (GREENPIN, LOW);
delay(500);
analogWrite (BLUEPIN, 255); // Blue
delay(2000);
digitalWrite (REDPIN, HIGH); // Black/off
digitalWrite (BLUEPIN, HIGH);
digitalWrite (GREENPIN, HIGH);
break;
case 4: // fade from blue to violet
for (r = 0; r < 256; r++) {
analogWrite(REDPIN, r);
delay(FADESPEED);
}
// fade from violet to red
for (b = 255; b > 0; b--) {
analogWrite(BLUEPIN, b);
delay(FADESPEED);
}
// fade from red to yellow
for (g = 0; g < 256; g++) {
analogWrite(GREENPIN, g);
delay(FADESPEED);
}
// fade from yellow to green
for (r = 255; r > 0; r--) {
analogWrite(REDPIN, r);
delay(FADESPEED);
}
// fade from green to teal
for (b = 0; b < 256; b++) {
analogWrite(BLUEPIN, b);
delay(FADESPEED);
}
// fade from teal to blue
for (g = 255; g > 0; g--) {
analogWrite(GREENPIN, g);
delay(FADESPEED);
}
break;
}
STEP 4: TEST!
make sure everything is working correctly and fix any problems you might have
STEP 5: Stitch It Up
once everything is tested you can stitch it up and take it out and play! For more fun you could add a buzzer to get that PEW! PEW! PEW! sound
It shouldn't be that hard. It might be easier with half-finger gloves or starting from the end of the LED strips back towards the wrist.
