Push Buttons wiring

Controls – Push-Button wiring

Our current Schematic uses Pins A0, A1, A2, A3 as input for the push buttons.

In the “2 player mode” the Arduino software uses A0 (Car 1) and A2 (Car 2).

In the “4 Players Mode” A1 is used for Car 3 and A3 for Car 4.

For a detailed description, see “Push Buttons Assembly” page in “Tutorials” section

4 Players Mode

4 Players adapter cable

To play with four cars (colors), you need

2 x Type 1 buttons (see above)
2 x Type 2 Buttons (see above)
2 x Dual Headphone Jack Splitter Stereo 3.5mm (see picture)

Insert the Splitters in the two Jack of the PCB (where you usually insert the two type 1 buttons)

On each Splitter insert one Type 1 Button and one Type 2 button.
