【Arduino】108種傳感器模塊系列實驗（資料+代碼+圖形+仿真）
實驗一百一十六：NRF24L01+ 無線模塊功率加強版 2.4G無線收發通信模塊黑金剛
1、安裝“Mirf”庫（下載鏈接 https://github.com/aaronds/arduino-nrf24l01）
安裝“rf24”庫（下載鏈接 https://github.com/nRF24/RF24）
2、項目測試：NRF24L01最簡單測試之Client 示例代碼
3、模塊接線
Arduino uno --- nRF24L01
3.3V --- VCC：模塊供電引腳
GND --- GND：模塊接地引腳
D7 --- CSN：接收端選擇引腳
D8 --- CE：發射／接受狀態選擇引腳
D11 --- MOSI ：控制端輸出，接收端輸入引腳
D13 --- SCK：時鐘信號
D12 --- MISO：控制端輸入，接收端輸出引腳
*IRQ引腳在本例中不需要接
