“Lets build a NRF transmitter using arduino
In this tutorial, I am showing how to build a MULTIFUNCTIONAL RC TRANSMITTER USING ARDUINO. This nrf transmitter consists of 2 joysticks 6 buttons switches and a gyroscope. so we can use this transmitter to control different RC projects. now let’s get started
Arduino Pro MiniThe Arduino Pro Mini is a microcontroller board based on the ATmega328.It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, an onboard resonator, a reset button, and holes for mounting pin headers. A six pin header can be connected to an FTDI cable or Sparkfun breakout board to provide USB power and communication to the board. The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with the Arduino Mini. There are two versions of the Pro Mini. One runs at 3.3V and 8 MHz, the other at 5V and 16 MHz.The Arduino Pro Mini was designed and is manufactured by SparkFun Electronics.
NRF24L01 Transceiver Module
nRF24L01 is a single-chip radio transceiver for the worldwide 2.4 - 2.5 GHz ISM
band. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and an Enhanced ShockBurst™ protocol engine. Output power, frequency channels, and protocol setup are easily programmable through an SPI interface. Current consumption is very low, only 9.0mA at an output power of -6dBm and 12.3mA in RX mode. Built-in Power Down and Standby modes make power-saving easily realizable.
Joystick*2 (joystick breakout)
The Joystick module is similar to analogue joysticks found in gamepads. It is made by mounting two potentiometers at a 90 degrees angle. The potentiometers are connected to a short stick centred by springs. This module produces an output of around 2.5V from X and Y when it is at rest. position
mpu6050MPU6050 is a Micro Electro-mechanical system (MEMS), it consists of a three-axis accelerometer and three-axis gyroscope. It helps us to measure velocity, orientation, acceleration, displacement and other motion
