Customer #127854 on COM-11752 - LED String Lights - Warm White (10M)
I removed the 39 ohm resistor that came with my soft white string and replaced it with two 100 ohm 1 Watt resistors in parallel (50 Ohms). I powered the string with a 9V DC adapter (just like...

Why is the GND and VCC shorted? it’s killing my voltage regulator! getting hot as hell

Is that OK to leave the battery attached to the project while charging or is it necessary to remove the battery and place it on a safe surface before charging? Thanks

Does it really contain 5 x 30 Pack of Jumper Wires (meaning there are 150 wires)? That would be so great. Please confirm

I have the same problem with mine, as well; monitoring the values while rotating the vane reveals that those two positions literally don’t report any value! Any assistance would be greatly appreciated…

Way too expensive relative to the likely uses you’ll get out of it. Use a model rocket igniter instead, way cheaper.

It shouldn’t be shorted, but there is a 33 ohm heater in there; it will draw 150mA at 5V.

I replaced the one in the kit with an opaque red one I had in a bundle of LEDs from radio shack. It’s much less intense and I still got to use the 330 ohm resistor in the kit.

Okay, Gonna make myself look stoooopid here, I’m sure. Just got the H-bridge today, eagerly popped it into a breadboard to check it out. I built the most basic of circuits: 1,2EN are run to the +5V...

I want to use a 3V coin cell to backup the RAM/RTC- I think that JP4 needs to be left open if I want to do this? I can’t see JP4 on the board, although it is shown in the circuit. Can you explain where...

If you’re using this board and not the newer version, the jumper you’re looking for is inline with the shorter row of headers. Opening this jumper will allow you to connect a coin cell to the VBAT pin...
