Motor shield for ESP-12E Introduction:
This is the first motor shield for ESP8266 based on ESP-12E.
The ESP8266 combines an 80Mhz 32 bit processor with 802.11 a, b, g and n support in both station and router modes at a fantastic price point, enabling a pervasive, low-cost Internet of Things. It comes in various different flavors and while oddWires hasn’t tried them all we have tried a lot. We decided to pick the latest version of the NODEMCU, the V2. The primary difference between the V2 and the V1 is the use of the ESP-12 module, which exposes GPIO 9 and 10 - another two GPIO pins come in very handy.
We also feel it is timely to offer this module as the Arduino IDE now supports the ESP8266. This is much easier to use than programming with other IDEs, although if you wish you can use the LUA scripting language. Pretty much all of the base Arduino functions are complete usable including, Wi-Fi, webserver, the GPIO pins, interrupts, EEPROM, Wire library (I2C), SPI, timers using Ticker, Servo, DS1820 temperature sensors, DHT11 sensors, MQTT, real-time clocks and others.
ESP8266 modules can be tricky to flash, but it’s a pretty seamless process using the Arduino IDE as, most of the time, the boards need no intervention to upload your sketch. Occasionally you have to hit flash/reset to upload.
Open-source, Interactive, Programmable, Low cost, Simple, Smart, WI-FI enabled
This NodeMCU development board contains a full ESP8266 WiFi module with all the GPIO broken out, a full USB-serial interface, and a power supply all on the one breadboard-friendly package.
This board is pre-flashed with NodeMCU - an open-sourced firmware with a few Lua script lines.
Examples of it's use:
Arduino-like hardware IO - Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware. Code like arduino or interactively in Lua script.
