uln2003 arduino pwm
Ardunio範例04：使用Arduino產生PWM 驅動直流小馬達 .... 橋就有電流放大的功能了，如果真的不夠用，的確可以再加放大電路，ULN2003很好用。,Hi, I want do drive 8 LEDs (3.6V, 50mA) with Arduino and ULN2003. Do I need to use sesistors to step down the voltage from 5 to 3.6V or is it ok ...

You could cut a 9 led length from a strip and wire that to your uln2003. For different colours on the 9 leds, maybe ws2812 leds would be easier. https://forum.arduino.cc ULN2003 - PWM led driver & 3 watt LED's - Arduino Forum
I made a nano board attached to ULN2003, runs at 12v into transistor array. If I calculate correct, 12v @ 250 ma = 3 watts [3 watts = (3) led ... https://forum.arduino.cc ULN2003 - PWM led driver & 3 watt LED's - Page 2 - Arduino Forum
When powered from 5volt, with 16* ~3.3volt LEDs @120mA each, (5-3.3)*0.12*16 = 3.26watt is lost in the chip. 1/3 of the power supply is lost in ... https://forum.arduino.cc |
