How to Program the Vexplorer Using Arduino

This instructable will be about using arduino to control the revell vexplorer. Later you can add as many sensors you want. If you don’t have most of the parts already this will cost you about $200 dollars. Most of the electronic bits you can find at radioshack and vexplorer at amazon, also arduino at the maker store.

Program the Vexplorer Using Arduino

Step 1: The H-Bridge

This link listed below will show you all of the step in constucting the H-Bridge. A breadboard will be sufficient if you have trouble soldering. Leave the motor leads and also switch leads open which we will be using later.
Depending on how many of the vexplorer motors you will be using multiple h-bridges will be required.


Step 2: Combining the Vexplorer

The vexplorer has 4 motors, but for this instructable will only be using 2. The motors that go to the wheel assemblies. Take the right motor’s positive and ground and attach the positive to one positive and ground from the h-bridge. Same with the ground. (See the first picture for details.) Then attach the wires that would normally go to the switch, to digital pin 13 and ground on arduino. Simply when we let the voltage go the motor will turn right and off for the motor to turn left. You can experiment by switching the polarity and getting different results. To power each h-bridge you can use the aux ports of the reciver. For powering the left motor you can use another h-bridge and follow the steps again. This is same with the arm and claw motors of the vexplorer.
