Career in Robotics

विद्यार्थी मित्रानो, तुम्ही अशी कधी कल्पना केली आहे का की एक प्रगत रोबोट तुमच्या घरी तुम्ही विकत आणलाय आणि तो तुमच्या घरातील जवळजवळ सर्व कामे अगदी बिनबोभाटपणे पार पडतोय? घर स्वच्छ ठेवतोय, कार धुवून स्वच्छ करतोय, तुमच्या घरातील किचनमधील सगळी…

Simple circuit of object counter using Arduino

This circuit can count number of persons entering a premise or number of objects passing in front of an IR sensor. The code works very nicely and fully tested in our lab. Note that a buzzer for short beeps is connected at pin-2 and the IR sensor is connected at pin-5. The delay in second "if" conditional statement is used to avoid accidental triggering of the sensor.

Beautiful decorative effects of LEDs using Arduino

This is a very interesting project, which you will love to construct using 8 LEDs and Arduino UNO development board. Burn the following code into your Arduino UNO development board and construct the circuit on breadboard as show in following Fritzing drawing. Then connect power to the circuit to see beautiful decorative effects of LEDs.

White Line Following Robot using 8051 Microcontroller

This a lab tested code of White line following robot using 8051 MUC. When there is black below an IR sensor, its output is binary-1. When there is white below an IR sensor, its output is binary-0. This code is suitable for OVAL SHAPED SIMPLE WHITE TRACKS. For complicated white tracks i.e. having many steep turns, USE POWER TURN INSTEAD OF SOFT TURN.

Edge Avoiding Robot using 8051 Microcontroller

This a lab tested code of Edge Avoiding Robot using 8051 Microcontroller. When there is depth below an IR sensor, its output is binary-1. When there is white surface below an IR sensor, its output is binary-0. This code is suitable only if the speed of the wheel motors is slow enough, otherwise the robot will fall from the table on the edge.
