IR Shield is designed for Arduino, which is equipped with infrared receiving and dispatching module, nRF24L01 interface, Xbee interface, Micro SD slot and temperature and humidity sensor. With this IR shield, you can intelligentize your home by making a DIY monitor for indoor temperature and humidity or a controller for IR home appliances such as air-condition and television.

  • IR_TX: 当D3设置为高电平,红外发射管会向外发射信号;当D3设置为低电平,红外发射管不工作。
  • IR_RX: 使用HS0038B作为IR接收模块。
  • Jumpers:跳线帽是直接连接到Arduino的IO 上,如果不需要或引脚被其他模块占用时,请移除其跳线帽。
A0:上拉一个10K电阻到A0按钮上。
LED1:连接到D6引脚,置高时LED1会亮。
LED2:连接到D7引脚,置高时LED2会亮。
  • Switch:根据Arduino主板的操作电平来设置,当主板工作在5V,开关打到5V;当主板工作在3.3V,开关打到3V3。
