“Have you actually read it yet, because your further posts seem to indicate you haven’t”
I have, I’m missing information for one simple reason (well mainly), I don’t have a multi-meter (going to get it today) I spent all the money on parts and forgot that all important tool. Other reasons will become obvious in my other responses.
“So if you short the signal wire to ground, the light changes?”
RIGHT- I will measure the output voltage of the signal wire and get back to you
“Why two regulators?”
The LED aray runs at 7 volts max, at least thats the battery configuration I took out of it. The second is to power the arduino, 12v regulated down to 5V, BUT I do have MB102 3.3V/5V Breadboard Power Supply Module which says it can take the 12v and turn it into 5v is this a better option than the regulator?
“If I guess correctly, using the switch, that was attached to this signal line, cycled through 3 brightness settings and off?”
“If so, how will the Arduino know what brightness setting is currently selected, other than by “dead-reckoning” using the number of times it has grounded the signal wire?”
I HAVE NO IDEA, other than the one you mention. I hadn’t thought about if the system had to read at a separate point other that full daylight. What I also need to be thinking about is how to tell the board what setting it is currently on, which will always be off at start.
“What is “the ambient light sensor code”?”
I didn’t think I really needed to include this information, all of that is arbitrary to the point of how to take the code information and use digital write to simply hit the switch, HOWEVER I do realize it may come into play when trying to calibrate the system to recognizing the state of the light array. I have not ordered the light sensor, I wanted to focus first on simply being able to turn the light on and on and on and off, lol. I thought there may be a way I could do that using the switch still, on a seperate digital pin,
read pin (push button) each button push would represent the stages of the light sensor, prior to the mention of reading the state of the LED array, using If then statement. If (button push) then (write digital LOW like mentioned before). Once I have the sensor I would change that segment of pin read write sequence to coincide with the sensor instead of the push button.
Hmm, ok so I have some more research to do. Look, Im real REAL new at the coding aspect.
I know how to measure sensor reads (obviously once I get that multimeter lol)
I know WHAT the components do and HOW they do it. I know how to define their operation in setup() and how to identify using the pins pinMode().
I’m going to go take some pictures of the setup I am working with and post them later, at this point I will return with more information, AND SOME ACTUAL CODE, so I don’t expect TOO much enlightening information, maybe some guidance on where to look to calibrate the board to know how many “clicks” to send down the signal line (and being able to count those, I will also test to see the voltage coming out of the signal line of the LED array.
