Tutorial 4: Working with ESP8266 WiFi Scan Class

WiFi scanner output

Working with ESP8266 WiFi functionality using Arduino IDE has been made surprisingly simple by the availability of the versatile ESP8266WiFi library that allows user to configure the ESP8266 as a WiFi network scanner, a WiFi station (connected to a WiFi network), a soft access point (creating it’s own WiFi network), etc. In this tutorial, we will explore the features of the Scan Class of the ESP8266WiFi library. The Scan Class allows you to scan and list the available WiFi networks in the range. In order to try this feature, open an example code from File->Examples->ESP8266WiFi->WiFiScan. In the example code, int n = WiFi.scanNetworks(); returns the

Tutorial 3: Connecting an OLED display to ESP8266

Interfacing an SSD1306-based I2C OLED to EasyESP-1

Whether you want to show sensor readings, implement a navigational user interface menu, or display diagnostic information during prototyping a project, a graphic OLED display is always a cool add-on to embedded systems. In this tutorial, we will learn how to interface an I2C monochromatic OLED screen to ESP8266 (we will use EasyESP-1 board) using Arduino IDE. The OLED display used in this tutorial is SSD1306-based that can be bought for ~$5 on eBay or Aliexpress. You can also get a similar I2C OLED display with a grove connector from Elecrow for plug-and-play interfacing with the EasyESP-1 board. Buy EasyESP-1 board Hardware Setup

Tutorial 2: EasyESP-1 “Hello World” Example

Connections for the “Hello World” example

After setting up the Arduino IDE to enable support for ESP8266, it’s time to write your first code for EasyESP-1 board. We will start with the classic hello world! example of electronics, a flashing LED. This is the best example to start with any new hardware platform as it gives us an opportunity to verify that the required software tools/drivers are installed properly and ready to rock. Hardware Setup In this example, we will connect the LD1 and D1 pins of J3 header together with a jumper wire as shown below. This will connect the LD1 LED near the bottom right corner of

Tutorial 1: Setting up the Arduino IDE for EasyESP-1

Adding ESP8266 support to Arduino IDE using Preferences window

One of the simplest way to program the ESP8266 chip on board EasyESP-1 is using the Arduino IDE. Following steps describe how to enable the ESP8266 support in the Arduino environment. Step 1 : Install Arduino IDE The first step toward setting up the Arduino platform for programming EasyESP-1 is to download and install the Arduino IDE. Go to the Arduino website and download Arduino IDE 1.6.11. Step 2: Install ESP8266 core package Next step is to install the ESP8266 core for Arduino IDE. It is an add-on that allows to write sketches for ESP8266 using the Arduino IDE  and its libraries. The easiest way

EasyESP-1: A rapid prototyping and development board for ESP8266

setup2featured1

EasyESP-1 is a rapid prototyping development board for the low-cost, WiFi-enabled ESP8266 microcontroller. With an onboard USB-to-Serial converter pre-installed, EasyESP-1 does not require any additional hardware to download your application firmware to the ESP8266 chip. The ESP module used in this development board is ESP-12E. All the I/O pins are broken out to 0.1” female headers for easy access, as well as to standard Grove connectors for connecting Grove sensors and other compatible modules. The 180-point breadboard further facilitates experimenting and testing of external circuits. You can buy EasyESP-1 from our Tindie Store. Non US buyers can also get it from
