Today we will use DHT11 or DHT22 for measuring temperature & humidity using Raspberry Pi. This sensor have three parts, Difference between both sensors DHT11 DHT22 Ultra low cost (Around 0.8 USD) Low cost (Around 2.5 USD) 3 to 5V power and I/O 3 to 5V power and I/O 2.5mA max current use during conversion […]
Today we will learn to use GPIO pin to glow LED using pythonscripts. Beauty of Raspberry PI is GPIO, General PurposeInput/Output ports. This can be used to give output or receive input. Prerequisite Note: RPi GPIO input voltage and output current limitations for GPIO pins: These are 3.3 volt logic pins. A voltage near 3.3 V isinterpreted as a logic […]
Today we will learn to use GPIO pin to Blink three LED 5 times using using While loop in python scripts Prerequisite Read my previous blog for basic understanding Basic understanding of Linux terminal commands Basic understanding python coding Basic knowledge of basic circuits Have connected 3 LED with resistor on Pin 17, 22,27. LED […]
Lets star Playing with Camera on Raspberry pi. We can use WebBased camera or Camera Module on Raspberry Pi. Even old Web camera of your desktop will also work perfectly. 1. Install motion tool on Pi apt-get updateapt-get install motion After installation check in /dev/ folder : ls will show video0 2. After installation edit motion.conf filenano cd /etc/motion.conf=========== Below given […]
