Hi guys,
i am very new to this design. i need to design a bluetooth module where in I give command from my phone and I get a some voltage as output end of the module.
So it is like
phone -> bluetooth module -> 5V
The bluetooth module will have batter pack so the module on receiving some command from phone should break or make circuit. How can I do this? Please advice. I want to keep to cheap and no unwanted items on pcb. I know I can use HC-06 , but it might be costly
