This is a quick project that uses NodeMCU with platform.io and coolterm.

NodeMCU Sing Along

NodeMCU is an open source hardware project that is equipped with ESP8266 wifi module. I created a simple webpage that has two buttons. When the buttons are pressed, a get request is made to the server created by the NodeMCU device. Depending on which button is pressed, a specific song is played.

Navigating Through Various IDE's for NodeMCU

I first went through Esplorer, then through Arduino IDE version 1.6.8, and finally has much success with platform.io and CoolTerm. Some issues ecountered with the Arduino IDE was with WiFi connection. WiFi connection was not reliable, even though there were no issues with blinking the onboard LED.

Installation - Pre Reqs

These set of instructions are for Mac OSX. The NodeMCU Github list the necessary software to install. You will also need to download Mac Port if you haven't already. Once you have finished the installation process, you should be able to see this port for the device:

$  ls /dev/tty.*
/dev/tty.SLAB_USBtoUARTport 

you should flash the firmware to the controller. You should then download esptool and pySerial in a virtual enviornment. From there you can move the bin file to the same directory as esptool.py. You would then write in the command line:

$ python esptool.py -p /dev/tty.SLAB_USBtoUART write_flash 0x00 nodemcu_float_0.9.6-dev_20150704.bin

Make sure that you are pressing the flash button the device. After you have successfully uploaded firmware, you are ready to try it in the Arduino IDE, Esplorer, and/or platform.io with CoolTerm.
