Complete Arcade Spinner

thingiverse

This is a complete spinner to use with an arcade cabinet. I use this with Mame. Even if there are other design. I had to develop it by zero. What you need. N°1 Leonardo Micro ATmega32U4 16MHz 5V Replace ATmega328 Arduino Mini Stock TE463http://www.ebay.it/itm/322097722501?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT N°1 Incrementale Ottica Codificatore a Rotazione 400 Impulsi / REV Rotary Encoderhttp://www.ebay.it/itm/181881354349?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT N°3 m3x10 N°1 m2x12 with nut Print the knob Print the flange Put this piece of code in arduino micro: include enum PinAssignments { encoderPinA = 2, encoderPinB = 3, clearButton = 8 }; volatile int encoderPos = 0; int lastReportedPos = 1; int encoderMove = 0; boolean A_set = false; boolean B_set = false; void setup() { pinMode(encoderPinA, INPUT); pinMode(encoderPinB, INPUT); pinMode(clearButton, INPUT); digitalWrite(encoderPinA, HIGH); // turn on pullup resistor digitalWrite(encoderPinB, HIGH); // turn on pullup resistor digitalWrite(clearButton, HIGH); // encoder pin on interrupt 0 (pin 2) attachInterrupt(0, doEncoderA, CHANGE); // encoder pin on interrupt 1 (pin 3) attachInterrupt(1, doEncoderB, CHANGE); // Serial.begin(9600); } void loop(){ if (lastReportedPos != encoderPos) { encoderMove = (encoderPos-lastReportedPos); //Serial.print("Index:"); //Serial.print(encoderPos, DEC); //Serial.print("--encoderMove:"); //Serial.print(encoderMove, DEC); //Serial.println(); if (digitalRead(clearButton) == LOW) { encoderPos = 0; } if ((encoderMove=-127)) Mouse.move(encoderMove, 0, 0); else if (encoderMove>127) Mouse.move(127, 0, 0); else Mouse.move(-127, 0, 0); lastReportedPos = encoderPos; } delay(10); } // Interrupt on A changing state void doEncoderA(){ // Test transition A_set = digitalRead(encoderPinA) == HIGH; // and adjust counter + if A leads B encoderPos += (A_set != B_set) ? +1 : -1; } // Interrupt on B changing state void doEncoderB(){ // Test transition B_set = digitalRead(encoderPinB) == HIGH; // and adjust counter + if B follows A encoderPos += (A_set == B_set) ? +1 : -1; } At the and you will be able to play Arkanoid with a nice spinner. Use A arduino pin 2 and B arduino pin 3. If need more help contact me.
