I like collecting 1/64 scale cars and was wondering how fast they are on my track. Using two IR Break Beam Sensors I can measure the time between both sensors being triggered and determine the speed. I can then also see if a heavier car is faster and if rubber wheels are better than plastic.
Parts needed
The following parts were used to build this
- Feather M0 Basic Proto
- FeatherWing OLED
- Feather Header Kit
- 2x IR Break Beam Sensor 3mm
- Breadboard-friendly SPDT Slide Switch
- Lithium-Ion Polymer Battery (optional)
- 4x 4-40 3/8" Machine Screws
- 4x 2-56 3/8" Flat Head Machine Screws
The Feather M0 can also be substituted with a Feather 32u4 Basic proto
Prerequisites
The following two guides should be followed to make sure the necessary drivers and libraries are installed in the Arduino IDE. The guides also show how to solder the headers on.
If you havent soldered before this is a great guide to learn how to solder.
