Using 2 different input pins for same trigger

Projects Programming
1

Hi - I am putting together an Iron Man helmet (from a design on Thingiverse).

The default code takes input from a switch to activate the servos to move the face plate up and down. I have a proximity sensor switch wired in on another pin. I can change the code so that the proximity sensor works, but only instead of the regular switch. How can I set both inputs to work?
In the code below the proximity sensor (TACTILE_KEY_PIN) is working. I just need the action_pin to work at the same time. Thanks.

#include "ServoEasing.hpp"
ServoEasing servoTop;
ServoEasing servoBottom;
const int action_pin = 2;
const int ledPin = 6;
const int potPin = A0;
const int TACTILE_KEY_PIN = 4;
int location = 31;
int bottom_closed = 107;
int top_closed = 167;
int bottom_open = 20;
int top_open = 20;
int value;
int maxBrightness;
void setup()
{
pinMode(TACTILE_KEY_PIN, INPUT_PULLUP);
pinMode(action_pin, INPUT_PULLUP);
pinMode(potPin, INPUT);
servoTop.attach(9);
servoBottom.attach(10);
setSpeedForAllServos(190);
servoTop.setEasingType(EASE_CUBIC_IN_OUT);
servoBottom.setEasingType(EASE_CUBIC_IN_OUT);
synchronizeAllServosStartAndWaitForAllServosToStop();
}
void loop()
{
value = analogRead(potPin);
maxBrightness = map(value, 250, 750, 0, 255);
if(digitalRead(TACTILE_KEY_PIN) == LOW)
while(digitalRead(TACTILE_KEY_PIN) == LOW);
{
if (location > bottom_open) {
servoTop.setEaseTo(top_open);
servoBottom.setEaseTo(bottom_open);
synchronizeAllServosStartAndWaitForAllServosToStop();
location = bottom_open;
delay(10);
analogWrite(ledPin, 0);

} else {
servoTop.setEaseTo(top_closed);
servoBottom.setEaseTo(bottom_closed);
synchronizeAllServosStartAndWaitForAllServosToStop();
location = bottom_closed;
delay(50);
analogWrite(ledPin, maxBrightness / 3);
delay(100);
analogWrite(ledPin, maxBrightness / 5);
delay(100);
analogWrite(ledPin, maxBrightness / 2);
delay(100);
analogWrite(ledPin, maxBrightness / 3);
delay(100);
analogWrite(ledPin, maxBrightness);
delay(100);
}
}
}

Thanks in advance! :slight_smile:

Use or (||) if either switch will initiate action or and (&&) if it takes both switches at the same time to initiate action.

if(digitalRead(switch1) == LOW || digitalRead(switch2) == LOW))
{
     // do something if one switch closed
}

if(digitalRead(switch1) == LOW && digitalRead(switch2) == LOW))
{
     // do something if both switches are closed simultaneously 
}

Welcome to the forum

You need to investigate the use of the or statement

if ((test1 == true) or (test2 == true))
{
  //execute the code here
}

Hi paulpaulson - not sure if I missed something, but couldn't see anyone else asking the question I am. Most people get stuck with the ServoEasing.hpp issue.

This seems to work, but needs an or and an and. Thanks for your help.

if((digitalRead(action_pin) == HIGH) or (digitalRead(TACTILE_KEY_PIN) == LOW));
while((digitalRead(action_pin) == HIGH) and (digitalRead(TACTILE_KEY_PIN) == LOW));

How are you coming along with the solution that was already posted?

if((digitalRead(action_pin) == HIGH) or (digitalRead(TACTILE_KEY_PIN) == LOW));

does absolutely nothing because the if statement ends with a semicolon. That terminates the statement.

@anon57585045 just posted an update :slight_smile:

Please do not update previous posts, it makes replies look weird.

I commented that line out and it works just as well without it :joy:

11

I didn't actually edit it, I just meant I had added to the thread, think we were posting at the same time.

12

Okay, but not much point in telling me about a post that I can just see...

Any remaining problems? Can you mark the thread solved by clicking on the solution?
