Simple Water Level Indicator

We have already posted about a Water Level Indicator and Controller using PIC Microcontroller. Today I am presenting a very useful, very cheap and very simple circuit using transistors for beginners in the field of electronics. This simple circuit can indicate the level of water in your tank using LEDs. Circuit Diagram Simple Water Level Indicator Circuit Diagram The connections and arrangements are made as shown in the figure above. The +9V is supplied to water using a metal contact.  In this circuit all...

LFC : Light Field Camera – Take your snaps.. Focus later..

You may have face a number of situations where the images you captured gets blurred. Or sometimes you may miss to click some valuable moments due to delay in focusing. Imagine a camera that doesn't need to focus before taking a snap. Just take some clicks at random. Don't bother whether it blurred or not. Microlens panel in LFC Light Field Camera, or called plenoptic camera, consists of a million of microlens to capture 4D light field information from all the distances, obtaining a...

Analog to Digital Conversion in ARDUINO

Analog to digital conversion module of ARDUINO UNO has 6 input ports. The number of the port varies with your ARDUINO model but the coding remains the same. The analog reading in the analog inputs are converted into corresponding 10bit(0-1023). ARDUINO developers have made such an option that you can print anything and see it on the Serial monitor. This example demonstrates analog input usage by reading an analog sensor on analog pin 0 and turning on and off a light...

Building Your Own PCB : Printed Circuit Boards

The electronic product construction technique for many is the printed circuit board, or PCB. There are a number of ways to build a custom printed circuit board. Good quality copper clad should be used for manufacturing of printed circuit board. Materials that you use to make printed circuit boards come in various forms. You can buy either single- or double-sided copper clad. Unless you’re making a double-sided board, stick with single-sided clad. The board that you use to make your PCB...

Automatic Garden Light Controlling System

Just like my previous circuit using LM358 this is also very cheap,also under 100 rupees. This is a circuit for controlling the street lights,garden lights,automatically. You don't need to turn it on and turn it off again and again,  just turn on the circuit once and forget, it will automatically manage itself by sensing the available brightness in the garden or street. Circuit Diagram Automatic Garden Light Controlling System Circuit Diagram Working In this circuit the IC LM358 is working as a comparator. The transistor BC548 is...

Laser Security System

Laser Security System

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, room etc.. By using different mirror arrangements you can form different security systems. This can also be used to protect more than one objects by suitably arranging...

Cell Phone Controlled Land Rover Using Logic Gates

What's Science for a small child ?At that age, no one of us is aware about the vast branches in science ,yet we are very curious to know.There will be lots of  Why's and How's in our mind which makes the elders irritated.By seeing a toy car,we always get wondered. Without knowing any robotics or electronics inside we just want to make our own toy car with clay and blocks.So its not wrong to say that every child has scientist inside...
