This is Simple and cheap approach to Line Following Robot, This do not have anymicro controller but just a simple basic Circuit on three 555 timers. It has a good efficiency on following all kind of curves. This Robot is no more than 1000PKR. To make a reliable and well functioning robot, you just not need Electronics Skills but also a little Mech

anical too. Having a Electronics mind, the most difficult job I felt in making this robot was Tires which would fit Properly in my motors and the Structure of Robot. For these stuff I accessed my University`s Lathe Machine for tires and a Wood Work shop to make the Structure. Does this circuit looks difficult to you ! wana go for a simpler than this !Click hereto see my Differential Drive based Line following Robot made on just BC108 Transistors. This is complete Diagram of whole circuit for Line Following Robot, but I have not shown the connections for LEDs, So for that, you will have to connect two LEDs in series of 1k resistor with +ve and -ve of this circuit. Dont feel that this is any difficult circuit, its very simple if you notice that Both 555 Timer circuits(others except center one) are exactly same. So you actually need to built the following two circuits. Our motors are not directly connected to the outputs of 555 Timer, but a transistor is used as a switch. The Pin Configuration of this transistor is (1)Emitter, (2)Base & (3)Collector I name this Part of the Circuit as Motor Driver Circuit, Now this is a circuit in which our DC geared motors are to be Hooked up, So wee need to make two circuits like this one in which The pin no 2 (Trigger) is given input from the Center 555 Timer Circuit In the above images It is configured as monostable, that means when they are triggered they give a pulse on the ouput pin...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
