Designed using Fusion 360. Print the top & bottom in your choice of color. Print the mid-section and lever in clear. Other things that you will need. Arduino Nano LED 3mm - 12pcs Screws, M3x8mm, Button Head or Socket Head - 4 Micro Switch - 1 Battery, 9v Battery Connector Silicone Wire, Various LED ground wires are soldered together in a circle LED + wires are fastened to PWM outputs, Opposite LEDs wired together as a pair I do not use resistors in this build. Instead, I use PWM to lower the current. Code to get you started: int On = 50; //Ms Time that the LED is on int cycle = 3; //# of times that the LED will flash void setup() { Serial.begin(9600); pinMode(3, OUTPUT); pinMode(5, OUTPUT); pinMode(6, OUTPUT); pinMode(9, OUTPUT); pinMode(10, OUTPUT); pinMode(11, OUTPUT); } void loop() { if (cycle == 1) { analogWrite(3, 100); //Orange delay(On); analogWrite(3, 0); } if (cycle == 2) { analogWrite(5, 130); //Red delay(On); analogWrite(5, 0); } if (cycle == 3) { analogWrite(6, 220); //Purple delay(On); analogWrite(6, 0); } if (cycle == 4) { analogWrite(9, 100); //Blue delay(On); analogWrite(9, 0); } if (cycle == 5) { analogWrite(10, 90); //Green delay(On); analogWrite(10, 0); } if (cycle == 6) { analogWrite(11, 110); //Yellow delay(On); analogWrite(11, 0); } cycle = cycle + 1; if (cycle > 6) { cycle = 1; } }
