This project is a car that can be controlled by an Android device. It works using a Bluetooth module, specifically the HC-05, and an Adafruit motor shield. An important part is to connect TX and RX of Arduino to their opposites on the module: RX and TX. To connect the HC-05 module, use male-to-female jumper wires. To connect it, we want to cut an end of the wire that is the male part and connect it to Arduino. Then fix the motor shield upon it. The steps are: solder wire at two terminals of the motor, connect the wires to motor shield, fix the tires to the motor, connect the module to the Arduino, fix the components on the chasis, power the Arduino and motor shield, and lastly upload the code. Now the car is ready to run. Download an application which has left and right mentioned in it, then connect it with HC-05 module.
