You can find the arduino library in the product link: https://www.electrodragon.com/product/ws2812-neopixels-ring-leds/ https://www.electrodragon.com/product/8-led-ws2812-5050-rgb-led-stick-board/ From the example, run "standtest" sketch, follow the instruction to setup for the board, and it will show all the standard effects: The wiring should be Din - pin6 of arduino, VIN - 5V arduino, GND - GND arduino. And here is...
Combined two items to together, the module from AC power source to 5V and 3v3: AC-DC AC 85-265V to DC 5V Power Module AMS1117-3V3 Regulator Module This is just a rough idea, you can make it much better. ( for example, Add some hot glue between the two broads to fix them.)
When you finished the design and manufacturing of your board, it is important to run a test to see if everything is working as expect, for many simple boards, this is done by human eyes check, but sometimes for more complex board, it is better to run a fully functioning...
We are working on some boards that can directly communicate with PC these days, so here comes with three most typical boards: USBASP: A wonderful programmer tool we have, do most of programming work, it also using V-USB interface. Atmega32u4 small breakout board: Similar to arduino leonardo and arduino micro, plug the...
This is a 5V 260mA solar panel board, with 5V voltage you can directly charge most USB device, althought the current is maybe only 1/4 of normal charger, but it is fun to try. See the images directly about how to build it. All items are available in our store.
We have found a nice video about how to to remove the solder from your soldered board, There are a few ways you can do so: Using Electrical soldering gun: easy, quick but expensive, not require any other tools. But now we don't have this item in sale. Solder Sucker: This...
