Main goal: using an IR remote, increment a PWM with preset outputs. It can be thought of just like a volume adjustment from the IR remote.
My hacked up code runs incorrectly. It waits for my remote button to run HIGH, and then it increments the counter every 2 seconds, then waits for the remote button again. I understand why, but I don't know how to control it. I believe I need control the count<5 inside 'for (count=0;count<5;count++)' to keep the loop from just running over and over. I want it to wait for the remote button before the counter increments again.
Any direction towards the goal is much appreciated!
Thanks

How do you want it to work?

I would like the counter to increment once after pressing the button on the remote.
I cleaned up the code a little to make it easier to read (functionally the same, though):
#include <IRremote.h>
const int analogOutPin = 9; //PWM (Motor) Output
const int RECV_PIN = 8; //RF Reciever input
int outputValue = 0;
int SpeedArray[5] = {254, 220, 190, 160, 145};
int count = 0;
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
// Enable the IR Receiver
irrecv.enableIRIn();
}
void loop()
{
if (irrecv.decode(&results))
{
if (results.value = 0x150C)
{
for (count = 0; count < 5; count++)
{
analogWrite(analogOutPin, SpeedArray[count]);
delay(2000);
analogWrite(analogOutPin, 0);
}
}
irrecv.resume();
}
}
I'll be honest, I've never used IR transmitter/receivers. Do you have a link to how your specific remote/receiver works? Mainly, I would like to know where the speedarray and 2 second delay come from. Once I know that, I might be able to help fix the problem.

Thanks for the clean up, I see what you did there.
I inserted the speedarray and delay. The delay will not remain, I will have different code there as I get stuff working.
And here is a link to the page I studied for using the IR remote with Arduino:
I took dronebot's IR to LED sketch, where he turns on an LED with a button from the IR remote, and started pulling it apart to do other things with it, like what I'm asking here.
Here is the IR_to_LED code from dronebot:

IRrecv irrecv(RECV_PIN);
decode_results results;
void setup(){
// Enable the IR Receiver
irrecv.enableIRIn();
// Set LED pins as Outputs
pinMode(LED_BUILTIN, OUTPUT);
pinMode(yellowPin, OUTPUT);
}
void loop(){
if (irrecv.decode(&results)){
switch(results.value){
case 0x150C: //Red Keypad Button
// Turn on LED for 2 Seconds
digitalWrite(LED_BUILTIN, HIGH);
delay(2000);
digitalWrite(LED_BUILTIN, LOW);
break;
case 0xFE8A75: //Yellow Keypad Button
// Toggle LED On or Off
if(togglestate==0){
digitalWrite(yellowPin, HIGH);
togglestate=1;
}
else {
digitalWrite(yellowPin, LOW);
togglestate=0;
}
break;
}
irrecv.resume();
}
}
Thanks for your time!
Ok, I'll assume you don't need delay at all, so I wonder if we can just remove it and adjust where we turn off the PWM:
#include <IRremote.h>
const int analogOutPin = 9; //PWM (Motor) Output
const int RECV_PIN = 8; //RF Reciever input
int outputValue = 0;
int SpeedArray[5] = {254, 220, 190, 160, 145};
int count = 0;
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
// Enable the IR Receiver
irrecv.enableIRIn();
}
void loop()
{
if (irrecv.decode(&results))
{
if (results.value = 0x150C)
{
for (count = 0; count < 5; count++)
{
analogWrite(analogOutPin, SpeedArray[count]);
}
analogWrite(analogOutPin, 0);
}
irrecv.resume();
}
}
Try that and see if it works
Nope. Not quite it. I think I need to control the condition of the 'for' control structure but I can't bring myself to figure out how.
The attachment shows what Arduino says about the 'for' control structure.
Each time though the loop the the control is tested. My case, I have counter > 5, so as long as the counter is less than 5, it continues counting until it reaches 5.
How do I count up per pulse of the remote button?
Thanks for the refresher, but I already know how for-loops work

Yes, the loop executes 5 times so that you call "analogWrite()" for each element of SpeedArray. Is that not what you want it to do?
Goat1985:

Create an integer variable and increment it (++) every time "if (results.value = 0x150C)" evaluates true.
Do you just want to increment once per button press? 0 - 4, then start over again?

Yes.
(I think I need to reevaluate how I ask for help. I'm confusing people, and I apologize.)

Sorry, that wasn't necessary for you, but so I could point out what I meant by saying "control", I meant the control for the for-loop.
Power_Broker:

This is what I'm trying to use the counter for. I'm not sure what that would look like inside the for-loop line of code?
(My sincere apologies for the confusion. I'll get better at getting to the point faster as I use forums more and more)

In that case, you shouldn't use a for loop. If you have a variable named "count" that never increments past 4, you can do "analogWrite(analogOutPin, SpeedArray[count]);" without the for loop. That is, assuming SpeedArray corresponds to individual and specific volume values.

Yes, SpeedArray provides the values that the remote button "steps' the output through. I will want one going down the array elements as well.
For that case, you will decrement the counter and continue to use it as previously mentioned
