![]() Red – Indicates whether the stick is in ON/OFF state.There are two LED’s in the circuit which acts as an indicator to the user. Note that you need to power up the Arduino from power bank by directly connecting it to the 5v pin of Arduino. The + and – from the USB cable needs to go into the + and – pins of +5Vcc as shown in the above circuit diagram. In order to connect them use a cut out USB cable to power this entire circuit. This powerbank is capable of delivering current up to 2A which makes this an optimum choice for this project. I have a used a regular power bank rated ( 5.1v / 10000mah) for this purpose. Power this entire project by using a portable power supply. This ESP module will provide WiFi connectivity to Arduino and let it to connect with mobile Phone or other WiFi enabled devices. 4.3 ARDUINO & ESP8266 MODULE:Īrduino will be the brain of this entire Light painting project. And I believe everyone knows that ESP8266 module is a simple WiFi developmental platform comes at the price of just $5. Check out this link to know more about these “ WS2812 RGB LED strip”. So a 60 LED’s will consume about 1500mA, so you must use a power source that is capable of delivering current more than this. So a single RGB LED will consume about 60mA. Remember RGB LED is a combination of Red, Green and Blue LED’s integrated in one package with each consume about 20mA of current. For the purpose of our project we are going to cut out 25 LED’s from the strip and use. Also do remember that this LED strip comes in 60 and 120 chained blocks. In our case it is going to be our Arduino. In this LED strip these individual WS2812 LED’s are chained together and can be controlled via one common timed signal from Microcontroller. Colors in this LED can be controlled via precisely timed signal. This LED has three pins Vcc, GND and Din to control the color of this LED. ![]() This is an RGB LED which consists of a control chip WS2812. They areĬircuits Library - 220+ practical circuits This project can be split in to three parts for the convenience of explaining. Check this article, it will guide you in basics of Arduino webserver and controlling things connected to it using a webpage. I have written a brief article explaining “ How to create a webserver using Arduino and ESP8266”. Once the LED commands are received, Arduino will process that and activate the RGB LED strip connected to it.ĭon’t worry if you can’t understand these.Then it will infinitely scan for LED commands ( will be explained in web interface section ) from the client.Once the client request is in, Arduino will send the webpage to client ( device browser) via ESP8266 module.Host the webpage in the Arduino itself and wait for external clients ( Device browser) to make the request.Create a server using the using the ESP board.Command ESP8266 to join our device WiFi hotspot.Here in this project Arduino with ESP8266 will perform the following activities This hosted webpage can be accessed via WiFi enabled device that is connected with Arduino and control the RGB LED strip connected to it. This webpage was designed in a way to take LED control inputs ( Colors : Red, Blue, Green and ON/OFF) from the user. Here Arduino will host a webpage and act as a server. This Light painting project is based on the concept of IOT where two networking devices connect with each other to form a network in turn establishing communication and control. Look up for the “RGB color codes here” and use it to get your custom color. It was added with a feature to input RGB code of any color as you wish like cyan,magenta, turquoise, olive, maroon etc. Custom Colors – Apart from the standard colors this stick is quite capable of generating any color as per the wish of Photographer.Standard colors – This stick is coded to emit standard colors like ( Red, Blue, Green, Gold, Rainbow, White ) using a simple button input.WiFi Operated – This light painting stick can be controlled ( turned ON/OFF, Changing colors ) very easily using a simple browser within any WiFi enabled devices.In order to overcome the above two challenges I have added the below features: This pixel stick was originally intended as a Light painting tool for photographers but its functionality is quite broader than that. I got this idea of making a Pixel stick or light wand which can light up in any possible color we can imagine and control it via local area network. ![]() Recently I have been working with RGB LEDs and found it really addictive because of the endless possibilities of colors and easy configuration. LED projects are always fun and fascinating. ![]()
