Outline Project: Microduino nrf24 communication Objective: To have a wireless control of the LED light via Microduino-NRF24. Difficulty: Elementary Time-consuming: Half an hour Maker: Microduino Studio-YLB Bill of Materials Microduino equipment Module Number Function Microduino-Core+/Microduino-Core 1 Used as a master machine to send the control signal Microduino-Core 1 Used as a slave machine to receive the control signal Microduino-USBTTL(FT232R) 1 For program download Microduino-nRF24 2 For wireless communication Other equipment Button 1 For function selection LED 1 For displaying communication status bread board 1 For circuit buildup Jumper 1 For circuit connection Module For ease of debugging and lowering the height of the module combination, here we need an extension board Microduino-Duo-V1. 201KIT Document Debugging

Step 1: Set up the system

Prepare master module: Microduino-Core+, Microduino-FT232R, Microduino-nRF24, a button and a bread board

Prepare slave module: Microduino-Core, Microduino-NRF24,Microduino Duo-V and an LED

Step 2: Set up the button Button connection: Adopt internal pull up. (You need to define it in program.) 201KIT-button

Step 3: Download the example program Download the program:

Choose "Microduino Core +(Atmega644P@16M,5V)" as the board of the master machine and "Microduino Core (Atmega328P@16M,5V)" as that of the slave machine, then download directly. download-core download-core+ Result Just download the program to the core board and you can control the LED on the slave machine through the button on the master machine. Note The sending and receiving parameters of Microduino-NRF24's communication function should be matched. The button adopts internal pull up, needed to be defined in program.
