I am using Arduino R3 for my Physics Laboratory Model where I want to read the toy cars speed (Initial speed and final speed) and the time it reaches from 1st Sensor to 2nd Sensor (IR Sensors)

The separation distance from the 2 sensors is prolly 9cm.

My problem is I didn’t seem to work, I used codes but it only reads its average speed, which is not okay because I need the Initial Velocity and Final Velocity.

Help me plssssss

Edit: I am a beginner with this but this project is required so yeah. Also another question, can I use the IR Sensors without it being plugged in at the breadboard?
