The abov given program of line follower robot is perfectly rut or not??? The job of the comparator circuit is to convert analog voltage output of the sensor into a digital format for the microcontroller to read. The table below shows the voltage at nodes Ahtomated and B for the possible orientations of the sensor module.

Automated Line Follower Robot

Out of the seven channels available in the IC,only two are used here. Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to Holding RST pin high for two machine cycles robof the oscillator is running foolowing the device.


Motor driver is used for driving motors because microcontroller does not supply enough voltage and current to motor. The comparator compares the analogue inputs from sensors with a fixed reference voltage.

The microcontroller, based on the inputs from sensor T1 say, left and sensor T2 say, rightcontrols the motor to make the robot turn left, turn right or move forward.

Line Follower Robot using Microcontroller: Project with Circuit Diagram & Code

Career advice and jobs related to electronics and IOT. Line follower actually senses the ta89c51 and run over it. Phototransistors T1 and T2 are used for detecting the white path on the black background.

Line follower robots were one of the earliest automatic guided robots. Interfacing Nokia Display to Micro Controller Moisture sensing automatic plant watering system using Similarly, comparator A2 compares the input voltage from phototransistor T1 with a fixed reference voltage.

Power Bank for Smartphones. Previous post Next post.

These capacitors are very essential and without them you can expect sudden crashes from the microcontroller side. Awesome Timer IC Projects. LM has inbuilt two low noise Op-amp.

This reference voltage can be adjusted by changing the value at89c511 the kilo-ohm preset. Reference design for Laser Drive Applications 6 December Output from the left and right sensors node Folllowing and B are connected to the non inverting input on the left and right comparators.

The current supplied by the microcontroller to drive the motor is small. The signal voltage at the inverting input of the operational amplifier is compared with the fixed reference voltage, which is formed by a potential divider circuit of 5.


Few rbot are unrecognizable. The sensor senses the light reflected from the surface and feeds the output to the comparator. There are four conditions in this line follower. It consists of mainly four parts: Can u send me the pcb file of line following robot using microcontroller.

Internship — Image Processing Engineer 27 December The task of the microcontroller here is to control the left and right motors according to the feedback signals from the left and right comparators so that the robot remains on the correct path the black line.

In this PCB layout we have designed a circuit board for line follower and 2 sticks for placing IR sensors. Basics, Usage, Parameters and Applications. When light falls on the phototransistor say, T1it goes into saturation and starts conducting.

Switch S2 is used for manual reset.

Embedded-Electronics: line follower robot using

A 12MHz crystal is used for providing the basic clock frequency. When the robot is back on track again, both motors are started. Output of the folloding comparator is connected to P1.
