Microduino Ward Calling System

Purpose The course will show you how to use Microduino to simulate a ward calling system. Equipment Module Number Function Microduino-Core 2 Core board Microduino-Core+ 1 Core board Microduino-OLED 1 For display Microduino-Cube-S1 1 Extension board Microduino-USBTTL 2 Program download Microduino-nRF24 3 Wireless network Microduino-Amplifier 1 Microduino-SD 1 Audio storage Other Equipment 10KΩ resistor Two Breadboard jumper wire One box micro usb cable One Button Two Breadboard One Loudspeaker One Schematic There are two senders—sender 1 and sender 2 in the picture—for patients to send signals. Modules to be stacked: Microduino-Core Microduino-USBTTL Microduino-nRF24 One receiver for nurses to check for patient help. Microduino-Core+ Microduino-USBTTL Microduino-nRF24 Microduino-Cube-S1 Microduino-OLED Program [MicroduinoHospitalCall] Debugging Step 1: Build the circuit according to schematic, as follows: Step 2: Download code and compile. Step 3: Supply power to any of the three stacked Microduino modules and the whole stacked system will be powered. Meantime, press button marked with sender 2 in the schematic and the readings will be displayed on receiver OLED: If readings showed on OLED were defined in the code, it means the calling of No. 25 patient is successful. Then press the button of sender 1, the calling of No. 24 patient is successful. The 16 hexadecimal of the picture showed on OLED is produced through PCtolCD. The detailed method can refer to: Lesson 2--Microduino OLED Usage Step 4: By adding voice prompt function, medical workers can get voice notice when someone calls. Stack Microduino-Amplifier and Microduino-SD on the basis of the three modules, as follows: Re-download MicroduinoHospitalCallReciverSound.ino program to Core+. Save audio files you want to play into SD card of Microduino-SD. As for how to make audio files, please refer to: Microduino LM4863 Music player -301KIT Step 5: since the three devices (Sender1, Sender 2 and Receiver) are far to each other, so we can consider to power on them with Microduino-BM. Result Here we make a simple wireless ward calling system. Video http://v.youku.com/v_show/id_XODUxNzM3OTYw.html
