Electronic Schematic Diagram of Light Detector Robot using Light Dependent Resistor (LDR)

Robometricschool. - When we tell about Light Dependent Resistor (LDR) component, so we can said that this is kind of light sensor that many used for many projects. One kind project that using LDR is Light Detector Robot.

Light Detector Robot define that the robot can run automatically follow the light that detected. It is similar with Line Follower Robot that will run automatically to follow the line. In here we want not to describe you how to make light detector robot, but we want to give you one electronic circuit schematic of Light Detector Robot using LDR based microcontroller AT89S51.

Electronic Circuit of Light Detector Detector

Figure 1. Electronic Schematic of Light Detector Robot (Image:Dendiatama)

Component Lists

All components to make Light Detector Robot can you see from figure 1 above. The components divided into 3 parts as follow:
  1. Sensor : Using LDR and IC LM335 or IC LM311
  2. Microcontroller : Using IC AT89S51
  3. Driver DC Motor: Using IC L293D

Schematic Performance:

To describe the performance or work of electronic schematic of Light Detector Robot as like in figure 1 above we can divide into three parts. In sensor, Microcontroller,and driver dc motor.

A. Sensor Part

In this part we use LDR as light detector or sensor. LDR will change the resistance when this component detect the light. With the circuit above LDR connected with the resistor to make voltage divider as output sensor. This voltage will be input in IC LM355 or LM311 that will compared with reference voltage. This IC used to make digital voltage in output from this sensor that used to as input data to microcontrolller AT89S51. 

We using two Light detector or sensor that can placed in the right and left the robot to detect light from light and left the robot.

B. Microcontroller

Microcontroller AT89S51 can used to controlled the input data from sensor part. We can program this IC using specific program like assembly or C programming to follow the logical how this robot will move when this robot detect the light from the sensor part. To program this IC you must have skill in microcontroller. You can use MIDE Programming Software and also ISP Programming to do it.

C. DC Driver Motor

This is the last part in this schematic. We can design dc motor driver using IC L293D to get 2 part DC motor driver. Data input this IC came from microcontroller and the output of this IC will be connected to DC motor that run the wheel of this robot.

So you can try using the Electronic Schematic Diagram of Light Detector Robot using Light Dependent Resistor (LDR) to complete your project. And if you get some error you can contact me or comment in this blog.

Reviewer Overview

  • Niloufer Tamboly, "I recommend this book for anyone pursuing a Certification like CWNA, CWNP or other wireless certifications. The technical concepts which are at the core of design, implementation, research, and invention of wireless communication systems are presented in an order that is conducive to understanding the general concepts, as well as those specific to current and evolving wireless communication systems and standards."
  • Steep, I've used this book through a course in radio communications at my university. I think the book is good for exactly what the title suggests - giving a basic insight to many principles and practice in the field. It describes and derives some formulas etc., but it does not give detailed knowledge in the mathematics, physics, electronics or propagation. The book is very much text-based, explaining principles instead of being very mathematically built. It works fine for instance when explaining the ground reflection two-ray model, but not so good when explaining the GSM codec.

Electronic Circuit Schematic of Touch Sensor using NE555

Robometricschool. - Maybe for a long time we didn't post again about electronic circuit schematic in this blog. So in this time we want to try give you again my posting about electronic circuit schematic of Touch Sensor using NE555 Based Proteus Software Simulation.

Maybe it is simple electronic circuit schematic that can be implemented in touch sensor for many using. Why we said that it is simple circuit because this circuit only need little components and only need little semiconductor components like transistor and integrated circuit. And specially we need integrated circuit for this circuit using NE555.

We will show you the schematic of Touch Sensor using NE555 according simulation result from Proteus program that used to design circuit and simulation. And here are all of circuit schematic of Touch Sensor using NE555 using Proteus Software.

Circuit Schematic of Touch Sensor NE555

Figure 1. Touch Sensor using NE555 Simulation before Touching (Image:leselektronika)
Figure 1. Touch Sensor using NE555 Simulation after Touching (Image:leselektronika)

Component List:

When tell about of component that used in Touch Sensor using NE555, you can see from all schematic like in figure 1 and figure 2 above. Main semiconductor in this circuit is NE555 that very easy to get in many electronic component shop. 

Performance of Touch Sensor using NE555

Global performance of this circuit schematic of touch sensor using NE555 as follow:
  1. When we touch the plat from input it will make LED D1 will turn on and 
  2. When we don't touch plat from input,it will make LED D1 will turn off.
And when we discuss the performance from electronic circuit schematic, we can describe as follow:
  1. When we touch the plat as input touch sensor medium, it will make transistor Q2 active and make IC NE555 will active to drive Q1. It will make transistor Q1 work like switch on ( close ) and make Relay active to turn on the LED D1.
  2. When we don't touch plat as input sensor medium, it will make transistor Q2 not active and make IC NE555 will not active. Transistor Q1 will not active and make this transistor work like switch off (open) and make Relay not active, and LED D1 turn off.
So all performance of this electronic circuit schematic of touch sensor using NE555 so simple and we can know work of this circuit when we simulate this circuit like using Proteus software. So when you want to use Proteus software you can take free download this software according many version as follow:
  1. Download Proteus 7.1
  2. Download Proteus 7.2

Recharge Gadget Battery using Solar Clothes from India

Robometricschool. - There are many ways to give solve the problem when our gadget battery is empty. One way to do it is provide recharge gadget battery easily from us.

Figure 1. Solar Clothes Illustration (Image:Detikinet)

Scientists from India develop clothes that can recharge gadget battery easily. Beside develop lingerie that can avoid from rape in women several days ago because many rape in India for several month ago, now scientist from India also develop with clothes theme recharge gadget battery using solar clothes

From solar clothes, it is can be used to save solar energy and than can be used to charge gadget battery like cellular or tablet. In sun clothes consist of solar cell and fan that planting in this clothes. Solar cell used to receive solar energy and fan used to make user always cool when use this clothes. So it is very nice.

According designer and photovoltaic system developer, Mr. Santipada GonChaudhury said that mini solar cell in planting in fiber clothes or in clothes pocket. From his design, that solar clothes can produce more than 400 watts of power with the help of mini solar panels. Size of embedded solar panels varies, ranging from 2.5 inch to 3 inch.

From this design that solar clothes can recharge gadget battery enough. The scientists describe their clothing will have two layers. One of them would be embedded two to four mini fan that will work utilizing solar energy. This concept is still being developed to make it more perfect. The scientists hope that this solar clothes could soon be mass produced and sold to the public. 

So it is one of useful clothes that will help you when you want to charge your gadget battery easily and suddenly. You must be patient to use it, because it is still in develop mass. (Source: Detikinet)
