This project demonstrates how to control a relay module using an ESP8266 microcontroller. A relay is an electromechanical switch that allows low-power circuits to control high-power devices. The ...

#define DO_LATCH 0 // set to 1 to allow latching relay 3&4 (need to change index.h as well) #define SKIP_DELAY 0 // set to 1 to skip startup delay ...

サーボモーターをスマホで遠隔操作するシステムを構築するためには、以下の要素が必要です。 ### 必要なハードウェア 1. **サーボモーター**: 操作したいサーボモーター 2. **マイクロコントローラー**: サーボモーターを制御するためのマイコン（例: Arduino ...

We know that ESP-01 is the best and cheaper module available in the market. As the title suggest, in this tutorial, we are going to interface a separate Wi-Fi module with the Raspberry Pi Pico. We ...

Abstract: This paper presents an insight into a Wi-Fi controlled car using NodeMCU ESP8266 module for car controlling, and ESP32 Cam Module, which collects the visual data, as well as maintains the Wi ...
