This is an LED driver which controls an LED strip with a remote and can change the colors/intensity of the lights. It supplies 12v to the LEDs.I want to know if it is possible to replace the IR receiv...
I'm building a hinged box where I'd like to trigger some leds in the box to turn on when the lid is opened, then off again when closed. My first thought was using a hall effect sensor. Is this...
Hello, I bought led strip that I plan to connect to a power bank. The strip is rated at 5v and has 144 WS2812B leds. The both sides of the strip have 3 pin connectors and 2 wires for ground and power....
I need to control a really small LED and use the thinnest wire possible so it looks hidden. Magnet wire is very thin and might work but I want to know if I can control an LED with it?
Looking for advice on improving this circuit. I use a 3S Li-Ion battery into a buck converter to power a Raspi trail camera with an on/off switch and led indicator.I use a largish resistor because I l...
Is there a way to connect 7 leds to only 1 pin on an arduino and be able to press 7 buttons which turn ON/OFF each of the 7 LEDs individually? I already know how to use an 1 analog pin for multiple in...
I have a ton of LEDs from a flashlight that need 4.5-5V to turn on, and I want to control them with my Raspberry Pi 3.3v pins (The 5v pins are already in use). It looks like I need an NPN transistor, ...
Hi,I'm looking for some help to see if a circuit is possible and how I would go about figuring what parts / power I would need ?I'm looking to design a circuit which features 7 LEDs ( ranging ...
