Time Measurement for Carrera Slot Car Track

 

After I had to have my own Carrera slot car track last year I soon wanted to have proper time measurement. First we measured time with a stopwatch app on the mobile – one driving the slot car and another one taking the time. But of course it is inaccurate and it was more and more becoming inaccurate as the night proceeded to fall – blame it on sleepiness, the beer or both *twinker!*

So I began to experiment with the MicroView – my first thing on Kickstarter I actually supported. It comes with an integrated OLED display and is fully Arduino compatible. To document the times I connected a mini thermal printer. I also added some push buttons to change the number of laps for one race and the number of players. Pressing this button changes the current player and the measured time is than properly assigned when it comes to printing the result.

Ingredients:

  • MicroView, https://www.sparkfun.com/products/12923
  • Mini Thermal Printer + thermal paper
  • Infrared Obstacle Avoidance Sensor
  • 5v switching power supply (Minimum 2 Ampere suggested for printer)
