About this product
A complete physics learning kit that measures object speed using two IR obstacle sensors placed at a known distance. The Arduino Uno times the interval between the gates in microseconds using micros() and displays the speed on a TM1637 4-digit display. This full version includes an Arduino Uno R3 compatible board and a USB A to B cable, so it is ready to build after the code is uploaded.

Frequently asked questions
Does the complete kit include everything needed to start?
The complete kit includes an Arduino Uno R3 compatible board, a 50 cm USB A to B cable, the IR sensors, the TM1637 display and a breadboard. You still need a computer with the Arduino IDE to upload the code.
Can I use a different Arduino board with this kit?
The kit is written for the Arduino Uno. Another Uno-compatible board can work if the pin connections in the wiring match the code. Boards with different pin layouts will need the code and wiring adjusted.
