Programming the car with the Electron
The Electron is a prototyping board from Particle which has a built-in GSM module. Using the GSM module, the Electron can connect to the internet using a 3G/2G network.
In the projects we have seen so far, the controller and the car are on the same Wi-Fi network. In this section, we explore a scenario where there is no common network between the controller and the model car that needs to be remote-controlled. How do we control the car remotely in this situation? We replace the Photon in the model car with the Electron. This allows the car to be in a completely different region and still be controllable remotely.
Putting it all together (again)
Connect the circuit as shown in the next schematic diagram. The connections are similar to the ones you did for the Photon-based projects. The Electron has to be connected to a Li-Po battery, which is included in the package when you buy the Electron. Make sure the battery is completely charged before mounting it...
