I'm [[user:rubin110|Rubin]], and am hoping to run at least 1 instant of this class. You can find me on #smart-home in the PS1 Slack.

= Power supply notes =
The WS2812B requires 5V to power the LEDs, as does the Wemos D1 board. Typically you will want to power both the strip and the board from a 5V power supply. For this short 1 m strip we're going to cheat and provide power to the LED strip from the USB port on the Wemos board. If you want to put together a new strip that's longer and requires more power you'll want to use a proper 5V power supply with more amps wired directly to the strip. Googling around you can find plenty of help on how to power strips. '''Do not power more than 60 LEDs via the Wemos USB port''', you risk frying the board.

Put shrink tubing around LED strip. Make sure the shrink tubing is at least 5 cm up and away from the end of the LED strip so you don't accidentally start shrinking it with the heat from the soldering iron

Apply flux and pre-tin 3 solder pads on the side of the LED strip with the arrows going INTO the strip.

There’s a power button in the top left. You’ll need to research how to have defaults setup for when WLED is first plugged in.

In the Effects column/screen you can select an effect to make the LED strip do cool stuff with the color palette. Try Phased. Some of the effects will have hard set color palettes of themselves. At the bottom of the effects screen there will be sliders to play with the speed of the effect or the intensity. Some effects will require a mic to be soldered into the board to do anything.

Moving WLED to a different wifi network, like at your house.
== Moving WLED to a different wifi network, like at your house. ==
When WLED cannot find the wifi network it was previously configured to it should open up its own wifi network where you can connect to and reconfigure the wifi network settings in the Config menu. Once moved you can use one of the WLED phone apps to scan and find the device on your wifi network.

If after 3 minutes you don’t see a “WLED” wifi network come up then you can plug the board back into a computer and go back to install.wled.me. When you tell the website to “install” again it’ll detect WLED already existing and offer an option to change the wifi network. Again note down the IP address, or try one of the apps.

If you have Home Assistant running, you can go to Settings > Devices & services. HA might auto discover WLED already on your network and give you an option to add the device. If HA doesn’t auto discover it, then just click Add Integration, select WLED, and provide the IP address.
