We often need to perform many simulations with Proteus, but there are many files that cannot be immediately found. I discovered some useful simulation libraries on The Engineering Projects blog.
1) Arduino Proteus Library
With this library, you can simulate Arduino boards in Proteus and design any type of circuit.
Arduino UNO
Arduino Mega 2560
Arduino Mega 1280
Arduino Mini
Arduino Pro Mini
Arduino Nano

2) Genuino Proteus Library
Genuino UNO
Genuino Mega 2560
Genuino Mega 1280
Genuino Mini
Genuino Pro Mini
Genuino Nano

3) GPS Module

4) GSM Module

5) XBee Module

6) Bluetooth Module
Bluetooth Module HC – 05
Bluetooth Module HC – 06

7) DS1307 Module

8) LCD Library
LCD 16 x 2
LCD 20 x 4

9) Ultrasonic Sensor

10) PIR Sensor

11) Gas Sensor
MQ – 2
MQ – 3
MQ – 4
MQ – 5
MQ – 6
MQ – 7
MQ – 8
MQ – 9

12) Flame Sensor

13) Vibration Sensor

14) Flex Sensor

15) L298 Motor Driver

16) Heartbeat Sensor

17) C945

18) Infrared Sensor

19) Solar Panel

20) Reed Switch Library

21) Rain Sensor Library
