Autopilot Drone

interface of Sensors

The DHT11 measures relative humidity. Relative humidity is the amount of water vapor in air vs. the saturation point of water vapor in air. At the saturation point, water vapor starts to condense and accumulate on surfaces forming dew.The DHT11 uses just one signal wire to transmit data to the Arduino interface diagram is shown in above fig. Using DHTLib library. It has all the functions needed to get the humidity and temperature readings from the sensor which is shown below program.

interface of Bluetooth module

here we use a Bluetooth module (HC-05) for bidirectional communication purpose, for turn ON the drone and to receive the sensor data's. two resistors are used as a voltage divider to step down the 5 volts to 3.3 volts so that Bluetooth can receive the data from the Arduino Uno. The circuit is so simple and small , there is only few connection to be made Arduino Pins Bluetooth Pins RX (Pin 0) ———-> TX TX (Pin 1) ———-> RX 5V ———-> VCC GND ———-> GND

Interface of Arduino Uno with flight controller

The flight controller (Cc3d) will provides 5 input control pins which gives the 4 movement actions to the drone they are throttle, roll, yaw, and pitch. These pins need a PWM signal to work, so we will generate the PWM signal using Arduino Uno. By proper planning and sketch of a particular are we can program the Arduino by calling function with delay.
