Arduion Split Flap GameDecember 13, 2012

When Arduino meets traditions, here the story of [the.anykey] and gift making.

We have a great Dutch tradition called sinterklaas (5th of december). For the older “non-believers” we make surprises. The purpose is to buy a small present but make a really cool “surprise” around it. Here my arduino based Split-flap game I made as surprise.
I made this for my 15-year old niece that was asking for very expensive presents only, so I thought I would make her a bit more price conscious :-)

The arduino (uno) used to run this all was tested to its limit 15 I/O ports :-)
- 5 pins for the score LEDs
- 4 pins for the stepper motor control, via ULN2003a
- 1 PWM pin for Servo to lock or unlock the side door
- 1 PWM pin for piezo speaker so we can make some sounds
- 1 pin for micro switch to align start of cards
- 2 pins for the lower and higher button
