Launch Proteus. Create a new schematic. Click on the (P button). In the Keywords box, type HC-05 or BLUETOOTH . You should now see the HC-05 module listed.
Since Proteus cannot natively send data to a physical Bluetooth device, you must simulate the serial communication: Virtual COM Ports : Use a third-party tool like the Eltima Virtual Serial Port Driver hc-05 bluetooth module library for proteus download
Note: Not all HC-05 libraries simulate the wireless pairing perfectly. Some only emulate the serial side. Read the library’s documentation. Launch Proteus
Right-click the HC-05 in Proteus and select a COM port (e.g., COM1). In the Keywords box, type HC-05 or BLUETOOTH
No. Most simple libraries only model a single module paired to a virtual COM port. For dual-simulation, you need a more advanced library like “HC05_MASTER” and “HC05_SLAVE” (rare).
If everything works, you’ll see the HC-05 symbol ready to drop onto your schematic.
void loop() if(Serial.available() > 0) incomingByte = Serial.read(); if(incomingByte == '1') digitalWrite(13, HIGH); Serial.println("LED ON");
