Topic: Ladyada's multi-button checker - how to? (Read 3223 times) previous topic - next topic


The code is send over ethernet to the second arduino.
Code: [Select]
if (justreleased[0]) {
      justreleased[0] = 0;
      Serial.print(i, DEC);
      Serial.println(" Just released");
Sometimes shows:
5 Just released
3 Just released
2 Just released
3 Just released
in the serial Monitor.
But also if i see for example "5 Just released" i receive the code in Mosquitto until it stops working.


Why are you explicitly testing the 0 element, and then printing i?

What are you REALLY trying to do?


I'm trying to figure out where the problem is.
I thought that:
Code: [Select]
if (justpressed[0]) {
justpressed[0] = 0;
Serial.print(i, DEC);
Serial.println(" Just pressed");
client.publish("foo/shower","0"); // Turn off Shower Light
// remember, check_switches() will CLEAR the 'just pressed' flag
shows me if the first button (pin 54 on the Mega) is pressed?
It's the only button that is connected at the moment.
But sometimes i get:
5 Just pressed
3 Just pressed
2 Just pressed
instead of "0 Just pressed" if i press button 0/54

The funny thing is that also if the serial monitor says for example "3 Just pressed", my button 0 code works.


You are testing the 0 switch, and then printing some random value of i. Why is that so hard to see? Or fix?
