Schematic of components and graphic image of those components will be in this section.Īrduino UNO R3: Arduino Uno is a microcontroller unit based on the ATmega328P chip. Short description of their working procedures, This section will provide an overview of the required components. Then the MCU that isĪrduino will process and analyze the signals to determine the corresponding signal for particular equipment and willĮxecute the instruction that is sent from the controller ( Figure 1).Ĭomponents required at the receiver to control LEDĬomponents required at receiver to control servo motorĬomponents required at receiver to control DC motor of a multipurpose RC vehicle After that, the corresponding signal will be passed to the nRF24L01 wireless transceiver module to transmitĪt the receiver unit, the receiver’s nRF24L01 will receive each signal and will pass to the MCU. Then it will process each corresponding signal to determine the particular signals for the receiving ends equipment. System Architecture and DesignĪt the transmitter unit, the controller modules attached with the controller MCU that is Arduino will receive control Types of equipment attached with the receiver) and will execute the instruction. The receiver unit will receive the signal or corresponding signal (if multiple signals are transmitted for multiple Send the instruction from controlling modules of the transmitter via nRF24L01 through the processing MCU calledĪrduino. In the controller, the transmitter unit will The designed controller here will be used to control a LED light,Ī servo motor and DC motors used in multipurpose radio controlled vehicle. Only have to changeĬertain control codes in the transmitter and receiver unit. That is why it can be used for multiple systems to control without being changing the circuitry. Transceiver module, the Arduino Uno R3 and other equipment used in the controller are easy to implement in a circuitry. Using this system any electrical and electronic equipment can be controlledĮasily by attaching equipment/s and injecting the relevant control code into the MCU unit. In the wireless control system, the nRF24L01 wireless transceiver module controlled with Arduino MCU is moreįlexible, low cost and user-friendly system. KeywordsĬommunication, Radio controller, Arduino, The receiver unit controls the attached equipment as per the transmitter’s direction. The controller is consisting of a transmitter unit and a receiver unit both build with nRF24L01 and Arduino Uno R3. It is a multipurpose radio controller that means it can be used for various purposes such as light controlling, servo motor controlling, DC motor controlling in radio controlled multipurpose vehicle, quadcopter etc. In this design project, a control unit is built with nRF24L01 wireless transceiver module and Arduino Uno R3 to control multiple types of equipment. It can be said that equipment can be controlled from a distance only with a controller in hand without being going near to that. That is we can control our electronics and electrical equipment from a certain distant part. Through the continuous development of wireless communication technology, it is now highly used in wireless equipment controlling. As wireless technology is very much easier to implement rather than wired, day by day its application is increasing. Nowadays wireless technology is one of the most common technologies used in our day to day life.
