![]() Steps for software setup Step 1: Download latest Arduino Software from Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. ![]() Let me clear you first Programming of IoT esp8266 is done in Arduino software and uses same commands that we use for Arduino Uno. Use of AT commands give you advantage of extra IOs of controller.ĭirect flashing of ESP8266 using arduino gives many benefits such as no need of external controller, Program memory of 1 M bytes and RAM of 80K Bytes, Makes simple hardware and software. Use of AT commands requires additional controller to generate AT commands. In this tutorial we are using Arduino software. ESP8266 Complete Circuit Software Setup for ESP8266ĮSP can be programmed using Arduino Software or using AT commands. Let’s move towards software requirements of ESP8266 and its setup. ESP8266 have PWM feature you can use it for fading the LEDs. To drive RGB LEDs, Relays use ULN2003 as driver IC. For 3.3V Serial voltage levels no need of D1 and R3 resistors. This is the complete hardware setup required to start with ESP8266. A favorite for that is the ESP-12, which has a shield (with FCC marking, but probably not registered at FCC) and also single channel 10-bit ADC. Some modules have etched antenna, some have ceramic antenna, and some have just a socket or a pin. The other ESP-12 modules expose more GPIO pins, but are packaged in SMT packages, at best with a 2mm-pitch notches. It also has an on-PCB Wifi Antenna etched on the PCB, which has sufficient gain for shorter range applications. With this board you will have very limited access to all-purpose GPIOs. This board exposes serial communication pins (RX/TX), and the minimal 4 control pins, GPIO0, GPIO2, CH_PD and ReSeT, plus VCC and GND of course. The Flash RAM size and chip model can vary.Īmong the ESP-XX boards, the most notable to get started is the ESP-12 and ESP-01, ESP-01 has a male 2×4 0.1“ pitch connector that can be readily used with Dupont wires. The boards integrate an ESP8266 chip plus a Flash memory chip (Flash RAM), a crystal, and usually on on-board WiFi antenna. Olimex has also started to sell their own boards, and you can find several others too. ESP8266 usually comes assembled on a board, the most popular ones having been the ESP-NN (ESP-12, ESP-01, etc) by vendors such as AIThinkers.
