Racelogic Lap Timer (Nextion 3.2")

This is another DIY Racelogic Laptimer with the Nextion 3.2 " Basic Display.

For best screwing options, i used the Ruthex M3 threaded inserts for fixing the Nextion Display with M3 screws (take the shorter threaded inserts for the display) and the normal ones for the rest.

The lid of the box needs a 1/4" threaded insert, because i used a camera mount, which is usually coming with 1/4 " screws. With this mount you have the maximum of flexibility by positioning the Laptimer.

For mounting at the rig, choose one of my mounts (as well with a 1/4" threaded insert).

The Arduino is fixed on the back side of the Nextion display with a piece of velcro tape, so it can be removed anytime.


Wiring is very easy:

Nextion > Pro Micro
5V (red) > VCC
TX (yellow) > RX
RX (blue) > TX
GND (black) > GND

For software installation, first install SimHub.
1.) Upload Nextion Micro Bridge sketch to arduino (it is in the simhub directory under 'Nextion Micro Bridge')
2.) Upload Nexti
