Go to the configuration page and click on browse to select the image.

Make sure you save the image as 24 Bit BMP. The Pixelstick LED Lightpainting Tool is a unique image enhancer that uses 200 RGB LEDs housed in an in a 73 wand that allows you paint images stored on an.

Make sure the image width (after rotation) is the same as the number of LEDs you have (e.g.

You have to rotate the image by 90° so that the bottom pixel row of the image is the first line to draw.

So you have to enter 14 here.īefore you upload an image to LED-Painter you have to generate an image with an image edititor of your choice. So D5 of the NodeMCU is GPIO14 of the ESP8266 but the Arduino definition is just 14.

Attention: LED Pin and Trigger Pin values are the integer values behind the Arduino Pin defines.

Click on Store to save the Settings permanent to the SPIFFS (as config.json) or click on Set Temporarily to store the settings in RAM.

Start with 20ms (which means an image with 500 px width takes 10 seconds to display).

The line time is the time each pixelline is displayed in milliseconds.

Else go to or if this doesn't work to the IP which your ESP8266 got from your AP.

After 10-15 Seconds connect to the AP "LED_PainterAP" with the password "ledpainter" and go to the url in your browser.

If you have not changed your settings in the source code, the controller will start in AP Mode after 10 Seconds since it couldn't connect to the default Station.

BMP drawing code is based on Bodmer's TFT_HX8357 example.Put your images to the data-folder of the project (or leave it as it is) and select "Upload SPIFFS image" to make the SPIFFS Filesystem ready.Compile the Firmware and upload to your controller.Edit the configuration initialization according to your settings (Config configuration =.Leave the setting because with the newer Arduino framework you might get issues with the webinterface (due to a bug in streamFile-Function). Edit the platformio.ini to match your board. Accelerometer/Gyro support for automatic animation at movement.Predefined patterns (like Rainbow, color gradient etc.).Fallback to AP when trigger button is pressed on Bootup.Automatic fallback to AP-Mode when the configured Wifi Station couldn't be connected.All configurations such as STA/AP Mode, number of LEDs, Pin for dataline of LED, Trigger-Pin, Image selection and time for each image row to be displayed are also be done in via Webinterface.The images can be uploaded via Webinterface.The images are stored on the internal SPI-Flash in the SPIFFS Filesystem.Direct BMP support, no special conversion tools are needed.The number and density of the LEDs can be determined by you. This project uses a cheap ESP8266 based Microcontroller board (like NodeMCU, WEMOS D1 mini ) and an addressable WS2812 based LED strip. Light painting is a technique to paint different patterns on a long exposure photograph by using a moving light source like a flashlight or in this case an WS2812 LED Strip.
