First time posting here and hoping someone can ease my mind. I’m tinkering with a project where I am trying to power 45 LEDs with the digital pins using PWM. I currently have them wired up in 3 sets of 7 parallel pairs that are behind 100 ohm resistors with the last 3 LEDs behind a 100 ohm resistor each. I’m hoping to power each of the three sets (7 pairs and one single LED) off a digital pin each but after reading some other threads on the forum, am worrying myself that this will be unsafe or potentially fry the photon.
I’ve modeled it and expect each digital pin to supply about 279 mA meaning ground will be sinking around 840 mA. I have some memory reading somewhere that the photon can supply up to 1 amp. However, I don’t recall where I saw this and haven’t been able to find it again. Is the Photon capable of this? Am I worrying myself needlessly or is this not a good idea?
