Hi,
this is my first post, I need help to create EM-18 RFID reader or ID-12, ID-20 reader, in Proteus, I want to use it as apart of arduino project's simulation.
are there any one have this component or can help me to create it?
You can simply use Proteus COMPIM and interface RFID, GSM, GOPS etc... to your PC and communicate with Proteus. Do not use MAX232 with COMPIM model. Also you should have a hardware COM port available in your PC and its COM port number should be between COM1 and COM4 then you can install eterlogic Virtual Serial Ports Emulator and create a mapper type device and map hardware COM1 to COM4 port to Virtual COM port assigned to RFID or GSM or GPS. You can have more than one COMPIM in your project for example. Mega2560 has 4 COIM ports so you can have 4 COMPIM in your project and interface 4 different Serial devices to Proteus.
