LM317 Variable Voltage Regulator Circuit

In this tutorial we will show you how to get the variable regulated Voltage from the LM317 IC. With a small circuitry attached with LM317 we can get variable voltage up to 37v with 1.5A max current. The output voltage is varied by varying the resistor connected to LM317’s adjustable pin.

Many people get confused with two terms XBee and ZigBee, most of them use it interchangeably. But this is actually not the case; ZigBee is standard protocol for wireless networking. While XBee is a product that supports various wireless communication protocol, including ZigBee, Wi-Fi (Wi-Fly module), 802.15.4, 868 MHz module etc. In this tutorial we are mainly focused on Xbee/Xbee-PRO ZB RF module which consists of ZigBee firmware.

Different Types of Switches and Their Applications

There are mainly two types of switches- mechanical switch and electrical switch. Mechanical switches require physical or manual contact with switch for operation. Electrical switches not require physical or manual contact, it has ability to perform operation. Electrical switches operate under the action of semiconductors.

Smart Blind Stick using Arduino

This Smart stick will have an Ultrasonic sensor to sense distance from any obstacle, LDR to sense lighting conditions and a RF remote using which the blind man could remotely locate his stick. All the feedbacks will be given to the blind man through a Buzzer. Of course you can use a vibrator motor in place of Buzzer and advance a lot more using your creativity.
