How to use the Arduino UNO board to decode the standard 433MHZ and 315MHZ signals and display them in hexadecimal？
Required materials：
Arduino UNO board, 1602A display, buzzer, adjustable resistance, QIACHIP RX18210A receiving module, DuPont cable, data cable.
Wiring notes：
| Number | Wiring symbol | Pin wiring |
| 1 | VSS | Ground |
| 2 | VDD | 5 v |
| 3 | RS | Arduino data terminal |
| 4 | R/W | Ground Read and write signals |
| 5 | E | Arduino data terminal |
| 6 | BLA | 5 v |
| 7 | BLK | Ground |
| 8 | D4 | Arduino data terminal |
| 9 | D5 | Arduino data terminal |
| 10 | D6 | Arduino data terminal |
| 11 | D7 | Arduino data terminal |
| 12 | VO | The middle pin of the third pin of the adjustable resistor |
| 13 | Buzzer positive pin | Arduino data terminal |
| 14 | QIACHIP RX18210A receiving module DAT pin | Arduino data terminal |
Arduino decoding code：
#include<RCSwitch.h>
#include <LiquidCrystal.h>
const int rs=13,en=5,d4=8,d5=9,d6=10,d7=11;
LiquidCrystal lcd(rs,en,d4,d5,d6,d7);
RCSwitch mySwitch=RCSwitch();
void setup() {
pinMode(3,OUTPUT);
lcd.begin(16,2);
mySwitch.enableReceive(0);
}
void loop() {
if (mySwitch.available()){
lcd.clear();
lcd.setCursor(0,0);
lcd.print ("receive:");
lcd.print(mySwitch.getReceivedValue(),HEX);
if(mySwitch.getReceivedProtocol()==1){
lcd.setCursor(0,2);
lcd.print("Protocol:EV1527");
}
digitalWrite(3,HIGH);
delay(500);
digitalWrite(3,LOW);
mySwitch.resetAvailable();}
}
