All our high-power LED options can be built on a linear design as well. We also offer QuadPod’s which can hold 4 high-power LEDs on a board slightly larger than the 20mm stars (see Fig. The boards are insulated and contain conductive tracks for easy circuit connections. Our 20mm 1-Up and 3-Up starboard designs are the best sellers. 1) or are mounted to a Metal Core Printed Circuit Board (MCPCB). High Power LEDs come as bare emitters (as seen in Fig. Cree tends to have higher listed Lumen outputs and is a market leader in the High-Power LED sector. Luxeon, on the other hand, has excellent colors and thermal control. Some prefer one over the other but that comes with experience and knowing what to look for. We carry high-power Surface Mount LEDs from industry leaders Cree and Luxeon. Both are excellent in our opinion, that is why we carry them after all. Read the current state of the limit switch to turn the LEDS on or off.Surface Mount LEDs are diode(s) that can be placed on a substrate (circuit board) with a silicon dome over the diode to protect it (see Fig. Turn the stepper motor to hit the limit switch put your main code here, to run repeatedly:

put your setup code here, to run once: Stepper steppermotor(STEPS_PER_REV, 8, 10, 9, 11) Any ideas on why this is happening?Ĭonst float STEPS_PER_OUT_REV = STEPS_PER_REV * GEAR_RED Individually these all work perfectly fine but when executed all at the same time only the motor works and the LEDs will only flash once when ive not even touched the switch.

I am trying to make a stepper motor hit a limit switch and then light up 6 LEDs.

How the led works
