Bluetooth Robot Mio

1- Robot Mio

2- L298N Voltage Regulator Dual Motor Driver Board

3- Arduino Nano

4- HC06 Bluetooth-Serial Module Board

5- (2x) 9 V Battery Head

Let's start with the motor driver connections first Let's solder the jumper cables under the in1, in2, in3, in4 pins of the motor driver. (as pic1)Then let's wire the cable in in1 to nano's d6 pin, in2 to d10 pin, in3 to d5 pin, and finally the cable in in4 to d9 pin. (as in picture 2)Now, let's make the connections of our HC06 module, let's wire RXD pin to TXD pin of nano, TXD pin to RXD pin, VCC and GND pins to any 5v and GND pins of nano. (as pic3)And finally, let's make the motor connections. When Mio is facing us, let's connect the right motor cables to the out 3,4 pins of the motor driver and the left motor cables to the out1,2 pins.Let's connect the red cable of the 9v battery cap to the VIN pin of the nano and the black cable to the GND pin. (as pic4)And let's cut a jumper wire in the middle, strip the end and connect it to the GND pin of the nano, to the GND pin of the motor driver. (as pic5,6)Let's connect the red cable of another 9v battery head to the 12v pin and the black cable to the gnd pin on the motor driver power pins. (as in picture7 )
