Hello friends, I hope you all are doing great. Today, I am going to share the ESP-01 Adapter Library for Proteus . It brings the famous ESP-01 adapter board to Proteus: the small 5 V board with a regulator and a level shifter that the ESP-01 plugs into, so that an Arduino UNO can use the ESP8266 Wi-Fi module with four wires and no extra parts. Your sketch sends AT+CWJAP , AT+CWLAP or AT+CIPSTART over a serial port, and the module scans, joins, serves pages and talks TCP and UDP, right inside the simulation. Updates ESP-01 Adapter Library for Proteus Latest version: V1.0 (October 2026, this tutorial) Other ESP8266 modules: ESP-01 · ESP-01S · ESP-07 · WiFi Shield · NodeMCU ESP32 boards: ESP32 DevKit V1 · ESP32-DevKitC V4 · ESP32-S3 DevKitC-1 · ESP32-C3 SuperMini · TTGO T-Display Helping Tool ...
