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 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.               FEATURES NXP KL25Z Kinetis KL2x MCU (MKL25Z128VLK4) High-performance ARM® Cortex™-M0+ Core 48MHz, 16KB RAM, 128KB FLASH USB (Host/Device) SPI (2) I2C (2) UART (3) PWM (TPM) ADC (16 bit) DAC (1x 12bit) Touch Sensor
