SELF DRIVING CAR USING AURDINO By DEVANANDA REDDY Here i'm going to instruct you about making an Obstacle Avoiding Robot based on Arduino. I hope to do step by step guide on making this robot in very easy way. An obstacle avoiding robot is a fully autonomous robot which can be able to avoid any obstacle which it face when it move. Simply, when it met an obstacle while it moving forward, automatically stop moving forward and makes a step back. Then it looks it's two sides left & right and starts to move the best possible way; which means either in left direction if there is another obstacle in right or in right direction if there is another obstacle in left side. The obstacle avoiding robot is very helpful and it is the base of many large projects such as Automatic cars, robots used in Manufacturing factories, even in robots used in spacecrafts.

Smartphone to Digital Microscope Conversion! By DEVANANDA REDDY The world is an interesting place, but it's fascinating up close. Through the lens of a microscope you can find details that you would otherwise never notice. But now you can. This instructable will show you how to build a stand for about $10 that will transform your smartphone into a powerful digital microscope. This DIY conversion stand is more than capable of functioning in an actual laboratory setting. With magnification levels as high as 175x 375x Edit: with the addition of a second lens magnification can be as high as 375x , plant cells and their nuclei are easily observed! In addition to allowing the observation of cells, this setup also produces stunning macro photography. The photos in this instructable were taken with an iPhone 4S. Watch the video below for a quick overview of the project! Step 1: Materials and Tools The cost of this p
