Rc helicopter tutorial pdf

Hey guys, this is a tutorial on how to make a transmitter that we can use to control RC plane, drone and other RC models using Arduino. Below you will find a diagram for the RC transmitter and the receiver circuit and also the coding for each of them.

Before uploading the code, make sure you have the NRF24 library important in your project. This should install the necessary library to use the NRF module.

Wait for the installation to complete before uploading the code. The schematic diagram for the Transmitter. Now let's talk a bit of what we have in this circuit. I am using an Arduino nano p to control the transmitter as it is relatively small in size to fit the transmitter. For this project, I am using the NRF24l01 with a power amplifier that has an external antenna for wireless communication.

Note that this might not be the best way for wireless communication as the range is often affected by interferences. However, with the amplified version of the NRF24, you can get a decent range of around m to even 1.

It is, however, easier to use this module. Receiver Schematics. For the receiver, you connect the Arduino same as we did earlier for the transmitter, I have added 3 different types of output for you to understand how it works. The first one is the led, which is controlled to be either on or off through the transmitter.

This is a digital output. The second thing is the servo, and the third one is a speed control dc motor. To control the speed of a DC motor, you must switch on and of the input of the motor at a very fast rate. The amount of time the switch is on and off determines the average voltage.

The higher the average voltage, the higher is the speed of the motor. If you want to make a drone with this transmitter and receiver, check it HERE. Transmitter code. This part of the code is the address of the transmitter. It is very important to make it the same as the receiver for it to be detected. I recommend copy and paste the exact thing to the receiver code which you will find below. So, I define it as above. This part is a function that is telling to map the values of the joystick to the PWM signal.

You should check the values of the lower, middle and upper position of your joystick and enter the values according to it. Rotor Blades. Fly it in RealFlight. RealFlight is the 1 RC flight simulator in the world!
