2. ESP8266 是深圳安信可科技有限公司开发的基于乐鑫ESP8266的超低功耗的UART-WIFI模块的模组,可以方便进行二次元开发,接入云端服务,实现手机3/4G全球随时随地的控制,加速产品原型设计。 二、硬件接线 1. 所用到的硬件有:Arudino Mega 2560, ESP8266-12F. 2. 接线如下表所示 三、硬件编程 1. ESP8266 芯片接收...
1)注意,我们将为ESP8266使用单独的3.3V电源。不要使用5V电源,不要使用来自MEGA的3.3V电源。 2)如图所示,将ESP8266与Arduino MEGA连接。 3)注意ESP8266的RX与MEGA的TX之间的连接。我们实施此电阻分压器是因为MEGA的TX的逻辑高电平为5V。我们必须为ESP8266降低3.3V的电压。否则,ESP8266芯片会烧毁!! 4)确保MEGA的...
ESP8266module is not 5V tolerant. It works on 3.3V power suplay. Most Arduinos works on 5V. If we want connect both components we need to adapt voltage levels between. If you are using 3.3V Arduino, then readESP8266 WiFi and 3.3V Arduino connection. First we need 3.3V power supply f...

Full integration on one board: Mega R3 ATmega2560 and WiFi ESP8266 with memory4 Mt bytes (32 Mt bit). All of the modules can work together or each separately. And everyone has their own pinout headers. The convenient solution for the development of new projects requiring Uno and WiFi. ...
ESP8266一块 Arduino NG一块(其它Arduino也可以) Arduino Mega 2560一块(其它有多个串口的单片机也可以) 杜邦线若干 2、基本原理 原理也很简单,Arduino Mega2560有多4个串口,把Arduino Mega2560当作串口数据的中转设备,并且在数据中转的过程中复制一份发送给电脑就可以了。
arduino开发esp8266定时器 esp8266 arduino定时器中断 实验中使用到的Arduino开发板型号为Mega 2560。Mega 2560的工作电压为5V,其标明的推荐电压为7~12V,在开发项目的时候,一般要用到变压器。其供电类型有3.3V和5V两种。这里进行中断实验时,没这么麻烦,只需将这块板子和电脑用USB线连接起来即可。
