This is a simple Micro-controller based car. The Micro-Controller is connected in the car. The Arduino is doing all this job. For receiving data wirelessly we are using the HC-05 Bluetooth module.
At first, We have to connect/ pair the Bluetooth module with the phone (Android) you want to control. Now, we are doing different operations such as when we press the forward button then the Phone sends a data value to Bluetooth module.
Next, we have to code in a way that if Arduino Gets a Certain Data (Suppose ‘F’ for forwarding) we have to make a certain condition for running the car in a certain direction. So, basically there are many switch cases in the Arduino code. For a known condition or a switch case, the car will perform the added functions in the code.
In the Same way, F, B, L, R are used for moving the car Forward, Backward, Left, Right movement.
