INTEGRATED DEVELOPMENT BOARD OF MOTOR
CONTROL
Students: Mr. Hitesh Khatri Mr. Dhiraj Mahajan
•Integrated development board which can control parameters of various different
motors
•The peripheral integrated circuit (PIC18F458) was used as a microprocessor to
generated step pulses for the stepper motor, an angle for the RC servo motor and
change duty cycle to vary the speed of the DC motor

DESIGN AND DEVLOPMENT OF TRAFFIC LIGHT CONTROLLER USING CONTROLLER AREA NETWORK
DESIGN AND DEVLOPMENT OF TRAFFIC LIGHT CONTROLLER
USING CONTROLLER AREA NETWORK
Student: HARSHAL S. HEMANE
 To solve the traffic congestion issue.
 Develop a traffic light control system
controlled by controller area network
(CAN).
 Traffic light controller operated by for
push button
 First and Second push button for
operational state working in specified
time
 Third push button for preoperational
state only yellow light is blinking
 Fourth push button for stop Red light is
on

Scotch Yoke Mechanism for Demonstration Purpose
 The Scotch yoke is a mechanism for
converting the linear motion of a slider
into rotational motion or vice-versa.
 The Piston or other reciprocating part
is directly coupled to a Yoke with a slot
that engages a pin on the rotating part
 The shape of the motion of the piston is
a pure sine wave over time given a
constant rotational speed
