Sorry – new to arduino and trying to understand basic rx tx. I’ve set up everything (the hardwired setup) exactly like you have yet the LED only goes on or off – the pot has very little control – definitely no smooth fading. Does the value of the pot matter? No idea what i could be doing wrong?

#include
#define Button 6
//int inPin = 6; //
int val = 0;
int old_val = 0;
int state = 0;
int val5 = 86;
AFSoftSerial mySerial = AFSoftSerial(2, 3);

void setup() {
pinMode(Button,INPUT); //
pinMode(13, OUTPUT);
Serial.begin(9600);
Serial.println(“Chip 1 online”);
delay(2000);
// set the data rate for the SoftwareSerial port
mySerial.begin(9600);
// mySerial.println(“Whats for dinner?”);
}

void loop() // run over and over again
{
val = digitalRead(Button); // read input value and store it. Yum, fresh
// check if there was a transition
if ((val == HIGH) && (old_val == LOW))
{
state = 1 – state;
mySerial.println(2);
mySerial.println(5);
Serial.println(“Rising Edge”);
delay(250);
}
old_val = val; // val is now old, let’s store it

if (mySerial.available()) {
Serial.print((char)mySerial.read());
}
if (Serial.available()) {
mySerial.print((char)Serial.read());
}

delay(50);
Serial.println(val); //

}
