A Raspberry Pi measures marble travel time using two photogates built from a photo transistor and a light source and Python code that polls the GPIO and records start and stop timestamps the project uses a Raspberry Pi Model 3 with the CanaKit starter kit and the RPI.GPIO package wired to GPIO 17 and 18 the IR LED proves too dim so battery finger flashlights replace it debugging includes multimeter checks and breadboard wiring and the kid runs ten trials per condition then analyzes results in a Jupyter notebook
