Description
Neopixel LEDs aka WS2812b addressable RGB LEDs are very fun to play with because it has integrated driver IC built in which allows us to control tons of such LEDs using one Data line from the microcontroller. That certainly a great advantage over regular LEDs. But What more interesting is that if it can be control over the internet. With that in mind I made this Neopixel LED driver board. I have used ESP8266 as the brain of this project so I can have wifi connectivity as well. But there is more, I have included a LDR for controlling the brightness automatically, depending on the ambient light. Along with that there is a DHT11 sensor for getting the current temperature. It also has a push button for changing different modes and what not. It also has a I2C port for connecting additional sensors like MPU6050 accelerometer & gyroscope sensor or DS3231 RTC sensor. I added a barrel jack for powering the driver board as well as the LEDs.
