Building an Arduino-based Follow Me drone

For this section, you will need the following things:

• Motors
• ESCs
• Battery
• Propellers
• Radio-controller
• Arduino Nano
• HC-05 Bluetooth module
• GPS
• MPU6050 or GY-86 gyroscope.
• Some wires

Connections are simple:

1. You need to connect the motors to the ESCs, and ESCs to the battery. You can use a four-way connector (power distribution board) for this, like in the following diagram:

2. Now, connect the radio to the Arduino Nano with the following pin configuration:

Arduino pin	Radio pin
D3	CH1
D5	CH2
D2	CH3
D4	CH4
D12	CH5
D6	CH6

3. Now, connect the Gyroscope to the Arduino Nano with the following configuration:

Arduino pin	Gyroscope pin
5V	5V
GND	GND
A4	SDA
A5	SCL

4. You are left with the four wires of the ESC signals; let's connect them to the Arduino Nano now...
