reads A0 pin data ,prepares a JSON and sends on serial line every 5 seconds
int id=99;
#include <SoftwareSerial.h>
SoftwareSerial sw(2, 3); // RX, TX
void setup() {
Serial.begin(115200);
Serial.println("Interfacfing arduino with nodemcu");
sw.begin(115200);
}
void loop() {
Serial.println("Sending data to nodemcu");
int adc=analogRead(A0);
Serial.print("{\"sensorid\":");
Serial.print(id);//sensor id
Serial.print(",");
Serial.print("\"adcValue\":");
Serial.print(adc);//offset
Serial.print("}");
Serial.println();
sw.print("{\"sensorid\":");
sw.print(id);//sensor id
sw.print(",");
sw.print("\"adcValue\":");
sw.print(adc);//offset
sw.print("}");
sw.println();
delay(5000);
