Webcam Interfacing with Raspberry Pi

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 the OS is reading the camera. Afer entering lsus…

LED Brightness Control using Touch Sensor and ARM

Hey Folks, In this tutorial, we will learn, how to change the intensity of light using touch sensor the ARM (FRDM-KL25Z).
INTRODUCTION The FRDM-KL25Z is an ultra-low-cost development platform for Kinetis L Series KL1x (KL14/15) and KL2x (KL24/25) MCUs built on ARM® Cortex™-M0+ processor. The FRDM-KL25Z has been designed by NXP in collaboration with mbed for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M0+ and the power of USB Host and Device.The FRDM-KL25Z is supported by a range of NXP and third-party development software.It is packaged as a development board with connectors to break out to stripboard and breadboard and includes a built-in USB FLASH programmer.

Soil Moisture Monitoring using ESP8266 and Soil Moisture Sensor

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.

Components Required:
LM393 Soil Sensor NodeMcu(ESP8266) Connecting wires(male to male) Breadboard  Follow the Image below for circuit connection reference:-

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 the circuit dump the code given below:-

#include <ESP8266WiFi.h>
const char* ssid = "Enter SSID";
const char* password = …
