I can’t understand how to connect my arduino pro mini Pro Mini
To my HC-05 Bluetooth module
There is a guide to connect them given here : http://www.instructables.com/id/Bluetooth-Serial-Adapter-for-Pro-Mini/
But it is for 5V version and involves shorting the diode on the pro mini plus a divider circuit.
Apparently, there is an obvious difference in the circuit according to my components.
Please help me connect them correctly.
