how do I send a signal of ground vs no connection?
I didn't read the "how to use" section. I apologize.
I am using the ambient light sensor code to detect light and send a signal based on values.
I am getting power from a 12v battery regulated to 7 volts, the board is powered to 5v through a separate regulator same battery.
Three wires, ground, power and signal (the signal wire being a simple ground switch)
The signal the LEDs use to run off of was a ground interrupt push button. I just need to know how to ground interrupt on an if statement
I don't have a multi-meter (going to get it today)
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?
I have not ordered the light sensor,
When you read the how to use this forum did you forget the bit about how to post code or did you only skim read it?
Well, Like I said, I read it, I have however, not really posted any code yet.
The board doubles as the holder. I could try to hack it.
