Hi i got some new LED strips i wanted to connect to my elongboard. I tryed to connect them to my rc reciver (the reciver for my controller). It works fine and i can turn the lights on and off using a switch on the remote. The problem is that the LED lights dont get enough power so they light up pretty badly. Any ideas how i can do this? want to be able to turn the lights on and off with the remote.
extra question: I have a SP110E LED Hue bluetooth controller for the light. Any good Apps i can use to get half the leds white and the other half red?
Because your lights are using a lot of current, the receiver (actually the ESC powering the receiver) isn’t powerful enough to maintain the 5 volts you need. Using a step-down converter directly from your battery will make sure your lights have enough power without dropping below 5V
Yes, a transistor and a resistor so that the receiver toggles power in the step down converter circuit. Others have probably done it on this forum before with a better explanation, but here’s what I did for my brother’s board:
Left side would be the output of your step down converter, and right side is channel 2 of your receiver
For me the lights still faintly glow even when the remote isn’t turning the transistor on, so I guess I picked a bad transistor
I am using Arduino nano powered off receiver. 40T provides power to LEDs. Channel 2 (steering) provides data input to arduino. Arduino provides data out to switch on LEDs and change colors/patterns based on channel 2 pot position.
Battery tube can swap 21700 or 18650 as necessary. One 40T should power the 64 nodes for minimum 3 hours.
Battery tubes can be assembled multiples in series to series more batteries. The DC barrel jack head can be swapped for an LED headlight, high power connector…etc, it’s modular…
I may have gone overboard on LEDs planning out for…144 addressable LEDs running off the main battery and another 6x T6 LEDs on a light bar. A car high beam is about 1200 lumens, this is about 6000 lumens total
I use these buck boards puts out 4 amps, Run my 5 volt headlights, WS2815 strips driven by my nano firefly variant receiver ESP32-lora (Droid), and brake lights and I also breakout a waterproof USB to the side of my enclosure to use to charge my phone, transmitter, tablet.
They even work with my 13S Board
then you use a 12" male to male usb to connect to the buck converter
I also use a micro usb version and a 4 way toggle switch (master/Slave) and 2 x 90 degree male microusb plugs for programming my duel vesc without opening my enclosure
Anyone know how i can change set the led lights color? want half the leds white and the other half red. The app i use now only allow me to set a solid color and it has a few presets, blinking in different colors. But nothing like i want it
Always keep in mind that there will be heat created by any step down converter. I used this ubec in combination with my 10s4p battery pack to power 60 WS2812B leds. It acts as a step down converter but at the same time provides a clean 5V source. I use a chinese led strip where the max power consumption is 0.5 A at 5 V for 60 leds (all leds white) and the ubec warmed up to 40 °C. On avarage it’s something between 0.3-0.4 A
