back to newbie again need help with switching led

am after making relay turn light on , off press of radio remote button. getting flashing fast when button pressed.

i getting in arduino scene after bad accident , memory has been affected normal able fly through finding hard recall memory.
so can me recall need do.

this code below. , know starting @ beginning. frustrating me trying learn walk again not knowing how move foot.

i need switch once it sees pin 7 change. if light on turn off , if off turn on.

i remember seeing b4 cant remember called or find it..

my starting code below works on tattie switch not on radio remote

code: [select]

int sensorpin = a0;    // select input pin potentiometer
int ledpin = 13;      // select pin led
int sensorvalue = 0;  // variable store value coming sensor

void setup() {
  // declare ledpin output:
  pinmode(ledpin, output);
}

void loop() {
  // read value sensor:
  sensorvalue = analogread(sensorpin);
  // turn ledpin on
  digitalwrite(ledpin, high);
  // stop program <sensorvalue> milliseconds:
  delay(sensorvalue);
  // turn ledpin off:
  digitalwrite(ledpin, low);
  // stop program for <sensorvalue> milliseconds:
  delay(sensorvalue);
}

your code making potentiometer change rate of strobing.

i think you're needing use state change detection setup.

i don't see potentiometer has turning on , off led.

can explain goal is, more clearly?

there no pin 7 in code.
