Working V8 engine with arduino and stepper motor

thingiverse

I made these upgrades of https://www.thingiverse.com/thing:1195361 project, adding some cool features: An undeneath box just for fit the electronics of an aduino Leonardo and the motor driver, The other pieces are a fan and the cover for the box, simply glued to their relative positions, A couple of flat head with exaust just to increase the reality of the engine. The motor is a stepper 5v chinese with geared box just fitted on the back of the crackshaft. About the electronics, an arduino leonardo and a ulm2003 are needed but every other arduino model work fine with the appropriate sketch, if you want to replay my project, simply copy and load this sketch to your arduino: #include <Stepper.h> Stepper myStepper(2048,8,10,9,11); void setup() { myStepper.setSpeed(14); } void loop() { myStepper.step(-20480); delay(3000); myStepper.step(-512); delay(1000); myStepper.step(-512); delay(1000); myStepper.step(-512); delay(1000); myStepper.step(-512); delay(1000); } with this sketch the motor run in loop: 10 turns in clockwise, wait 3 second and run 4 step every 90° to show the firing order. Simply connect to your usb and enjoy
