My first question is how do I power the LEDs but control them from the UNO R3?
Second, can I power the Pump directly from the UNO R3 or do I have to get the motor shield?
Seeedstudio BT Shield (to control the fountain via phone)
what is the equivalent for AC current?
Well what would my options be then? How would I pulse that many LEDs controlled with Arduino?
Ok, Mosfets are for DC current, what is the equivalent for AC current?
how rapidly do you need to pulse your LEDs
do they get pulsed all at the same rate or individual different rates, or in independently pulsed groups?
Also does the pulsing of the DC pump to create the drips need to be varied/controlled by the Arduino independently, or could it be a known constant pulse and the lighting pulses are varied only?
I know I can't power either the lights or the pump from the arduino but I want to control the lights.
What I don't know is how I can control AC current through arduino to flash the lights at the speed I need.
So why the obsession with flashing lights with AC?
QuoteSo why the obsession with flashing lights with AC?Because I want to be able to plug it into the wall and have the fountain turn on. I need to convert the AC to DC then, then control it with the Arduino? (Which still I don't know how I'd do that).
then control it with the Arduino? (Which still I don't know how I'd do that).
