Solar Tracker system Using LM358

Abhay Bajpai — Sat, 06 Apr 2013 12:54:15 +0000

We all know that a Solar Panel can be used to convert light energy to electrical energy. The amount of converted energy depends on the amount of light falling on the Panel. Generally Solar Panels are stationary devices which is fixed at a position. The produced electrical energy can be increased if we move the […]

Line Follower Robot – without using Microcontroller

Abhay Bajpai — Thu, 21 Feb 2013 06:51:35 +0000

After a long time I am presenting my new project Line Follower Robot without using Microcontroller. It is a simple circuit with a LM358 op-amp and is able to operate from 9v to 12V. The LM358 contains two op amps which are wired as comparators. Thus when the voltage at the non-inverting terminal (+) is higher than inverting terminal […]

Laser Security System

Abhay Bajpai — Sun, 16 Sep 2012 05:31:39 +0000

Here is a simple and cheap Laser Based Security System, which costs below Rs. 100. It is a simple circuit using LM358 OP-AMP and LM555 Timer. This circuit is triggered when the Laser beam falls on the LDR interrupts, which sounds the buzzer connected to it. This can be used to protect your valuable items, money, […]
