Getting Bluetooth Working With Jy Mcu Bt Board V1 06 Electronics

Also when i removed the jy mcu no fluctuation appear on lcd.

Jy mcu arduino wiring diagram. I used it to connect a arduino leonardo and an android tablet running. The bluetooth module we ll be using is called jy mcu bluetooth board module 4 pin. Jy mcu enc28j60 arduino nano v3 0 wiring karl november 24 2016 here is the wiring configuration you will need if you wish to connect this commonly found ethernet module to an arduino nano v3 0. It was worth the challenge to save myself 50 for a simple spp serial port rs232 emulator service.

I have jy mcu with v 1 06. Finally got around to using the hc 06 jy mcu bluetooth serial module. Basic configuration of the cheap jy mcu hc 06 bluetooth module linvor using an arduino uno and a pc. It is incredibly simple to wire up and cheap too.

It s pretty cheap at this time costing only 5 97. I measure the voltage at lcd voltage fluctuation is between 4 5v to 3 9 v. I connected jy mcu with arduino uno using softwareserial also i connected lcd with arduino uno. I m writing this instructable because i have had nightmares getting this cheap but well built bluetooth module to work.
