Fig. 3 shows an ESP32 module. Fig. 3: ESP32 (NodeMCU) The ESP32 serves as a controller and web server, generating PWM signals via its general-purpose input/output (GPIO) pins to control the motor’s ...
It integrates an LM317 positive regulator with a simple 8-bit PWM DAC topology to obtain a robust 11-V, 1.5-A capability. It thus preserves simplicity while exploiting the built-in fault protection ...
Using NodeMCU ESP8266 for controlling switches (Relay). Uses RTC (Real Time Clock - DS3231) and NTP (Network Time Protocol) for maintaining time. OLED Display (128x64) for instant updates. A webserver ...
This is a simple Lua script example for GGreg20_V3 / GGreg20_V1 ionizing radiation detector module with SBM-20 GM tube working under NodeMCU firmware on ESP32 / ESP8266 Using NodeMCU ESP8266 for ...
