What is it?

LF-Timegate is a time measurement device developed to assist with Line Follower and Line Follower Drag competitions during the XV ROBOTIC ARENA. It features circuit lap measurements and sprint measurements in one package with ±1ms accuracy.

Measurement modes:

For more information, read the setup guide.

What MCU does it use?

None.

To ensure reliability and simplicity, it utilizes 10 CMOS 4000 ICs to make all the magic happen.
