Introduction: How to Use Arduino and a RF 433 Long Range

Picture of How to Use Arduino and a RF 433 Long Range

I just explain how i have use the 433MHz RF Long Distance Transmitter / Receiver Pair and a arduino to install it on my rc truck for a firework ignition, lamp , pan tilt camera systeme .........

Step 1: MATERIAL YOU NEED

Picture of MATERIAL YOU NEED

1 ARDUINO UNO

1 433MHz RF Long Distance Transmitter / Receiver Pair

1 MOSFET TRANSISTOR

2 POWER 9V BATTERY

1 PUSHBUTTON

1 MOTOR OR LED OR WHAT YOU WANT !!!

Step 2: WIRING THE TX

Picture of WIRING THE TX

Transmetteur (tx) was easy to wiring

in the first time i have only use the puschbuton on the d0

after i have use the 4 " data " input

its not realy data its just a on/off sending

Step 3: WIRING THE RX WHIT ARDUINO

Picture of WIRING THE RX WHIT ARDUINO

wiring the d0 output of the rx to the A0 of the arduino

wiring the gate of the mosfet to the pin 13 of the arduino

the source to the gnd and the drain to the motor or other thing like lamp or firework ignition....

Step 4: THE CODE

#define mosfetPin 13

int on = false;

void setup(){

pinMode(mosfetPin, OUTPUT);

}

void loop(){

if (analogRead(A0) > 1000 && on == false) {

digitalWrite(mosfetPin, HIGH);

on = true;

}

else if (analogRead(A0) > 1000) {

digitalWrite(mosfetPin, LOW);

on = false;

}

delay(250); }}

Step 5: ENJOY !!!!
