RGB Graphic Equalizer driven by ESP8266

Amir Avni has shared the details of his cool RGB graphic equalizer build, which is controlled by the ESP8266 hardware programmed with the NodeMCU firmware. The RGB LED strings are controlled through WS2812, while the equalizer colors are chosen through a Web interface over Wifi.

Two weeks ago I got my ESP8266 Version 12, which is a new version of the ESP8266 micro-controller with more GPIOs, so it seems some nice things can be done with it. If you haven’t heard of the ESP8266 check this older postfrom the blog. Also, I got the MSGEQ7 chip, which is a chip that outputs an analog equalizer from a sound signal. I was looking for a fun project to do with those two items, one which can help me also to learn LUA script, the language that is used to program the ESP8266. Finally, I’ve created this project: An equalizer display controlled by ESP8266 with the NodeMCU firmware, where the equalizer colors are controlled via WiFi. Check the video:

Electro-Labs has posted a new DIY ESP8266 Development Board project to experiment with PIC microcontroller and ESP8266 module. The board features LCD display, pusbuttons, indicator LEDs, GPIO extension, FT232RL USB-UART converter over a Mini-USB connector, and 5V-3.3V bi-directional level converter circuits onboard.

A simple IoT demo using ESP8266 and Arduino

ESP8266 is a highly integrated serial-to-wifi tranceiver chip that can be used to connect any microcontroller with a serial port to a WiFi network for Internet of Things (IoT) applications. The best part of it is that the breakout board for this chip costs only $3 on Ebay, and the chip itself can be programmed/customized for a complete IoT solution. This instructable describes a simple demo of using the ESP8266 and Arduino to send temperature measurements to a remote webserver using WiFi connection. In this example, the remote server is ThingSpeak and the tenperature sensor used is Maxim’s DS18B20.
