This tutorial is about the clicking photos and recording videos using "Logitech Webcam C110 with Raspberry Pi 3 Model B" Component Required: Rasberry Pi 3 Model B  Logitech Webcam C110  Adapter Charger micro USB-b Type 5v,2Amp  Connection Diagram: Step 1: Create a new folder First, we create a new folder just to store your photo and videos separately. Open the terminal. Command for creating new folder is "mkdir folder name" Step 2: Check everything is up-to-date To update your Raspberry Pi command is " sudo apt-get update ". And to upgrade your Raspberry Pi command is " sudo apt-get upgrade". Step 3: Check SSH and Camera enabled To make sure SSH and Camera enabled. Follow these two-steps. By this command, you can configure your SSH and Camera " sudo raspi-config ". Enable SSH. Enable Camera. Step 4: Check connection of Camera Make sure the camera is connected. Then run this command to make sure...

Hey folks In this tutorial, we will learn how to interface LM393 module(Soil Moisture Sensor)with NodeMcu(ESP8266). LM393 is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module plant waterer device, so that the plants in our garden without people to manage; Adjustable sensitivity adjust the digital potentiometer (shown in blue) Operating Voltage 3.3V-5V; Module Dual Output mode, a simple. LM393 Soli Moisture Sensor Module(over view)  Components Required: LM393 Soil Sensor  NodeMcu(ESP8266)  Connecting wires(male to male)  Breadboard  Follow the Image below for circuit connection reference:- (Interfacing all components)  Here Pin A0 of the moisture sensor module connects to pin A0 on the ESP8266 The GND pin on the moisture sensor module connects to a GND pin on the ESP8266 The VCC pin on the moisture sensor module connects to a 3v3 pin on the ESP8266 D0 pin remain disconnected After making th...
