Cool and cheap remote control solution with Arduino!

This set is really cheap which only $4.3 (including receive module and remote console)! and work with Arduino!

It has four buttons on the remote controller, and you only need to connect four data output pin to your arduino analog read, VCC and GND to your arduino as well, then you can start to read signal!

The antenna is already mounted, just unbend it to increase receive distance, really easy to use!

The code is simply modified from Example library – Basic – AnalogReadSerial, compare the code below with example

[c]void setup() {
Serial.begin(9600);
}

void loop() {
int sensorValue = analogRead(A0);
int sensorValue2 = analogRead(A1);
int sensorValue3 = analogRead(A2);
int sensorValue4 = analogRead(A3);
Serial.print(sensorValue, DEC);
Serial.print(";;;");
Serial.print(sensorValue2, DEC);
Serial.print(";;;");
Serial.print(sensorValue3, DEC);
Serial.print(";;;");
Serial.println(sensorValue4, DEC);
delay(500);
}[/c]

About distance

In real test, the distance is over 2.5 meters with 100% data receive, but it could vary due to the different environment.
