<p style="justify-content: center"><strong>An Electronic System or circuit must be able or capable to “do” something and Sensors and Transducers are the perfect components for doing this.
Devices which perform an “Input” function are commonly called Sensors because they “sense” a physical change in some characteristic that changes in response to some excitation, for example heat or force
and covert that into an electrical signal. Devices which perform an “Output” function are generally called Actuators and are used to control some external device, for example movement or sound.</strong> </p>

Due to COVID-19, Govt. of India announced the Lockdown from 22 March 2020 to 3 May 2020. The end date is also depends on the position of COVID-19. So this assignment is in between this period. Currentlly i dont have lab acess right now.

<p style="justify-content: center"><strong> The seven segment display consists of seven LEDs arranged in a rectangular fashion as shown. Each of the seven LEDs is called a segment because when illuminated
the segment forms part of a numerical digit (both Decimal and Hex) to be displayed. An additional 8th LED is sometimes used within the same package thus allowing the indication of a decimal
point, (DP) when two or more 7-segment displays are connected together to display numbers greater than ten. </strong> </p>

to light up six of the LED segments corresponding to a, b, c, d, e and f. Thus the various digits from 0 through 9 can be displayed using a 7-segment display as shown. </strong> </p>

There is two DC motor are using to run a fan in kitchen chimney. The motor is around 5W rating, so i will use relay to controll the motor, because if I will directly connect thic motor on the board, due to high current
the microcontroller may get damage, so here I have the motor relay to ON and OFF the motor. Relay is connected with the microcontroller i.e. ATtiny-44.This is actually the proposed board.
There will be littel bit changes I may do according to need. </strong> </p>
