Blynk + ESP8266 ESP-01 Control GPIO13 LED

Blynk + ESP8266 ESP-01  Control  GPIO13 LED 

目的:

使用ESP8266  ESP-01+ 3.3V/5V Adapter + Arduino UNO 利用Blynk APP 控制 GPIO13

硬體 (電子元件):

1)麵包板 x 1 , 杜邦線 若干

2)ESP8266  ESP-01 Board x 1

3) 3.3V/5V Linear Regulator Voltage x1   (3V3/5V 電源模組)

4) Arduino UNO Board x 1

軟體: 

1)Arduino IDE 1.6.5版本

2) RealTerm 軟體

3) Blynk APP  

4) Blynk APP   API KEY  + WIFI  SSID PASSWORD 

接腳說明：

• 3V3：電源正極 ( 3 ~ 3.6 V )
• GND：電源負極
• TX：串列資料傳送接腳
• RX：串列資料接收接腳
• IO0：低準位：Flash Mode
• IO2：GPIO ( 未來開放 )
• RST：低準位時晶片重置( 一般浮接就好 )
• EN：晶片致能接腳( 就是接 VCC )
