Prevent loading new track/tournament if some rounds have been ran #44

Closed Pimentoso closed 4 years ago

It might be a good idea to block the user from reloading a new track or tournament if some rounds have been played. It would mess up everything. The user should be forced to use the 'new race' button and reset everything.

Fixed in #46

Hi Michele I'm attempting a build of the mini4wd chrono for our local club and I have some questions. I have some basic understanding of electronics, but I need clarification on the wiring diagram.

1) please confirm - resistors on the green LEDs are 220 ohm

2) the Photo sensor TEMT6000 has 3 connections. In the photos I can see 3 wires going to it, but on the circuit diagram there are only 2 and it does not say where to connect them - OUT, GND or VCC

3) is the resistor for the photo sensor 10K ohm? Is that right for the TEMT6000 and which of the 3 connections is it connected to?

4) what are the green LEDs for? I can't see reference to them in the documentation. Do they turn on to start the race?

5) I've got the laser diodes. I guess that these are powered the whole time. Can I plug these straight into the 5v power pin on the arduino? Do I need any resistors inline with these?

thanks for your help.

We're excited to have this running for our races.

thanks
