Abstract

The aim of this project is to develop the transmitter and receiver for the remote control helicopter. Firstly, the type of helicopter that has been used is a nitro remote control helicopter with the brand name of ―KYOSHO‖, and the control parts for this helicopter are limited for only 4 to 6 channels. In this project, the type of wireless technology that has been selected is the radio frequency communication. Then, the development process can be divided into two main parts which are the circuit development and the program development. The circuit development is a part used to explain on how the circuits for transmitter and receiver are developed by using the Fritzing software. While for the program development, it is a part used to explain on how the programming for the transmitter and receiver are developed by using the Arduino Software (IDE). Besides that, the flowcharts for all of the programming are also included to explain on how the program works. This project involves with two testing parts, which are the servo motors setup test and the data transmission range validation. For the servo motors setup test, the movement of each servo motor has been observed to check whether the connection is right or wrong based on each particular channel. While for the data transmission range validation, the transmitter and receiver has been tested to determine their maximum transmission range. Based on the results obtained from data transmission range validation, the maximum range was up to about 120 meters for the homemade transmitter and receiver, while the transmission range was only 80 meters for the existing transmitter and receiver. However, the existing transmitter and receiver are more sustainable since it can be used to control the airplane and the helicopter system. Lastly, the suggestions for the future works are to upgrade the homemade transmitter and receiver to function up to 6 channels, stabilize the function of data transmission by adding the bypass capacitor, and also stabilize the voltage supply by adding the voltage regulator.
