5. Science and technology are the things most needed by the people in
this era of globalization in order to meet the necessities of life.
Science and technology continue to evolve over time, so that the
community needs can be easily met.
There are still a lot of trash scattered about the environment around
us, but we know that with littering would lead to disaster and
disease, By Utilizing Technology and Apply it on the Project Smart
Trashbin aims to draw attention to the environment to dispose of
waste in place. The Smart trashbin is truly smart, could provide a
warning if the bins were full and can be opened automatically if our
hands brought closer to the sensor. Smart Trashbin has led and lcd
as an indicator if the bins were empty and full.

This Project worked if someone pass in front of the trash bin,ultrasonic sensor
will detect the distance,we set the distance in less 10cm so if someone pass
less 10 cm from the trashbin,ultrasonic sensor will work and moved the servo
motor, so that the trash bin will be open,and the Green LED will On,and if the
distance more that 10cm the trashbin will keep closed and the Red LED will
On.
And if the volume of trash in the low position the Green LED will On and will
show an output in LCD Display “BERSIH ITU SEHAT,TERIMAKASIH”,and the
last the Red Led Will On if the volume of trash in high volume and the Buzzer
will On,and the output in the lcd display is “ PERHATIAN !!! Sampah Penuh”.

Arduino Uno
Arduino/Genuino Uno is a microcontroller board based on the ATmega328P . It has 14 digital
input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz
crystal, a USB connection, a power jack, an ICSP header and a reset button.

11. 8
Buzzer
A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical,
or piezoelectric. Typical uses of buzzers and beepers include alarm devices, timers, and
confirmation of user input such as a mouse click or keystroke. Specification: 23mm diameter, 3.5
KHz drive external piezo buzzer. 5V – 12V.

LCD Display
LCD (liquid crystal display) is the technology used for displays in notebook and other smaller
computers.

Ultrasonic Sensor
An Ultrasonic sensor is a device that can measure the distance to an object by using sound waves.
It measures distance by sending out a sound wave at a specific frequency and listening for that
sound wave to bounce back. By recording the elapsed time between the sound wave being
generated and the sound wave bouncing back, it is possible to calculate the distance between the
sonar sensor and the object. Specification: HC-SR04 is an ultrasonic ranging module that provides
2 cm to 400 cm non-contact measurement function. The ranging accuracy can reach to 3mm and
effectual angle is < 15°. It can be powered from a 5V power supply.

Servo Motor
A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or
linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for
position feedback

17. The Procedure
13
Prepared All the tools and material that we’ll
needed to make this project.
First Step
find out the module&code of every component.
After we find out all the module,we try the code of
every component to test all the component to make
sure that no error,to test the script program we should
use arduino apication
2th Step
Combain all the script porgram of every component
become one scipt programs,and upload the
script,before upload the script,connect Arduino to
computer used USB cable.
3rd layer
Connect every cable on all the component,and conncet
them to the pin on arduino,and assamble all of the
component on the prothoboard or PCB for the fix script
program.
4th Step
Made the desain to trashbin,and placed all the
component to the trashbin.
5th layer
After we finnish do the step,try the project,pass
in the front of trashbin with distance less than
10 cm,and we can see an output.

25. Analysis
25
At the time of the trash in a state of stand-by (the cover of trash can closed), which lights up green (no 1,
indicator for the trash not full yet) and red light (no1, indicator for cover of the trashbin can closed) when our hand
getting close ultrasonic sensor ( ultrasonic sensor 1), then the cover of trashbin opened and the lights turn green (1 &
2, No. 2 indicator for trash can opened) If the trash is empty, then the green light (no one on and the lCD will display the
words "Bersih itu sehat. Terimakasih".
If the trash is full, the led will turn red light (no 2 will light up) and the LCD will display the phrase
"Perhatian,Sampah Penuh".

26. Conclusion
26
Arduino Uno can be a controller in this experiment, depending on the script programthat has been created.
Datasheet of component is really needed in the trials. The Ultrasonic censor can be detect the distance. The module of
all materials is needed. On datasheet, If the distance of 1 to 9 cm, the cover trashbin can opened and green LED turn
on. If the distance is more than 9 cm, then the cover trashbin will closed and red LED turn on, meanwhile the green LED
turn off.

27. Suggestion
27
If we want detect the volume of the trash with 3 variable,low,middle,and high,it’s use 2
ultrasonic sensor and set with different distance.
We can used 2 buzzer,for volume of trash and for the cover of the trasbin when the
cover of trashbin opened the buzzer will turn on.
