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.
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...
