= Example 01 - Servo Control / Node 00 - Potentiometer = There’s a useful section linking on to other APIs not included in the standard setup – some particularly interesting examples include Blynk, the widget-based gui builder with Android support that let’s you control devices over the Internet, and Adafruit’s NeoPixel library.Arduino Wireless Network - Multiple NRF24L01 Tutorial Other libraries include servo support (up to 24 supported on any available output pin), DNS, SPI, SSDP, and I2C. Thre are many differences here if you’re coming from a NodeMCU Lua-based background, somewhat more familiar ground if your coming at this with Arduino experience, but either way a must-read. You’ll absolutely want to review the ESP8266 Arduino Core documentation, a great resource covering Digital and Analog IO, timing and delays, the Serial object, use of WiFi, some ESP8266 specific APIs, and much more. Open your serial monitor to see the IP address that your board has been assigned, and connect to it with your web browser. Try some of the HelloServer sketch example – load it, enter your SSID name and password in place of the dots here: You’ll find all the example code under File / Examples under the Examples from Custom Libraries section Rename the D1_mini_Examples-master folder to D1_mini_Examplesĥ. Open the zip file, and move the D1_mini_Examples-master to your default Sketch directory (if you’re not sure where that is, open File / Preferences and it’ll tell you there)ģ. Download the Samples zip file from GitHubĢ. Voila, you’re all set! Well, you might like to get some sample code to play with of course. Once complete, select Tools again, and choose the WeMos D1 from the Boards dropdown. Wait for a while, while the Board Definitions and Tools are downloaded – and note, you can use this same download to support a whole heap of other boards, including the WeMos D1 mini, the Adafruit HUZZAH ESP8266, and the NodeMCU ESP-12E dev board that I’m so, so fond of.Ħ. In the Boards Manager window that appears, enter ESP in the Filter your search… box, click on the esp8266 by ESP8266 Community entry that appears, and then select Installĥ. Select Tools, mouse over your currently selected board, and choose Boards Manager from the popup menuĤ. In the Additional Boards Manager URLs text box, enter and hit OKģ. I’m going to presume you already have at least v 1.6.5 of the Arduino developer environment set up on your PC – if not, visit the Arduino Software page, download, install, then come back here. If you’re running Linux, you’re in luck – no drivers required. Both platform’s drivers are available on that link. Install the latest Ch340G drivers if you’re on Windows or Mac. I’ve grown comfortable with Lua as my development environment for ESP8266 chips over the past few months, but just this week one of my friends worked hard to convince me that being able to use HTTPS support via Arduino Core, flashing my ESP’s with that firmware and using the Arduino development environment was going to tbe the way to go. With the same barrel connection for power and (most importantly) same headers for hats, the obvious differences are the micro USB port in place of the Uno’s mini USB connector, and the delightful WiFI enabled ESP8266 chip on the D1, instead of the usual Atmel ATmega328P microcontroller. The D1 board is the same size as a traditional Arduino Uno R3, shown side by side above.
