Hi All, new to all this and trying to help my son with a invention project for school.
We are trying to operate a 12v pull solenoid with a PIR motion sensor and Arduino uno.
We have the PIR sensor hooked up tot he Arduino and tuning a simple LED on and off.
We have played with the sketch as far as changing the milliseconds and the LED light on duration does not change. We have also changed the adjustment on the PIR sensor. This does change the duration of how the long light stays on.
The issue is, we basically need the led to blink on and off almost instantly.
Our goal is to replace the LED with a pull solenoid, but we need the solenoid to open and close pretty fast to allow a ball to roll and then close to hole the rest of the balls in place.
any help appreaiated as the finish line is approaching fast.
