In reply to mustapha. Above project is based on PIC microcontroller, not for Arduino.

In reply to Quang Trường.

It shouldn’t. 2 transistors are added for logic level conversion… bluetooth module is 3.3V logic while PIC is 5V…..
so adding transistor to shift 3.3V logic to 5V will give more reliable circuit.

In reply to Sulayman kujabi. Did you successfully implemented them??. Is there a problem with the code.

Why do I see transistor in LAYOUT diagram but in SCHEMATIC diagram you don’t draw it. Without them, does it affect the circuit.

In reply to Lawrence Woods. We didn't tested it in proteus.

Is there any way I can obtain the Proteus schematic already completed? If not I’m not able to find the parts that are labeled relay which look to me like transformers? Can I download those parts somewhere?
