Ok so I finally after many hours got both my ESP-01 to have a 3rd GPIO [4] and it works great. I can use GPIO2 and GPIO4 but now my lack of programming skills are coming into play.
I am using the following sketch that I modified [or at least tried] to work with 2 LEDS instead of just 1 on either GPIO2 or GPIO4
Browser output is as follows
In attachments
When I click LEDR or LEDB on they both come on and when I click either LEDR or LEDB they both go off
I am sure I am missing something simple but I can't for the life of me figure out what I am missing so they work independent of each other

Code: Select all

if (request.indexOf('/LEDR=ON') != -1) {
digitalWrite(ledPinR, HIGH);

// Set ledPin according to the request
//digitalWrite(ledPin, value);
// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.print("LedR pin is now: ");
