In the city of Chihuahua,
Chih, we have a problem with the accumulation of garbage on the streets. This
doesn't just happen because of the fact that there is a lot of trash to begin
with, but the culture of not throwing our garbage in the trash bins. So, how
can we get more people to throw their trash into the bins, rather than into the
Here at EcoFun, we have
come to a fun solution to this problem.
We are developing a series of trash bins
that integrate a sound system and a Display. These will reproduce a particular
melodies in particular dates) or phrases (like thank you, good job and such), and simulate
a score board when someone throws garbage into any of the bins, in order to
make this act a lot more fun. Also, all the bins will be connected through a
wireless connection, and an alert signal will indicate when a bin is
full by turning on a led indicator, and will send a message to a central
computer, in order to be emptied.
Our objective is not only creating conscience on the problem
of throwing garbage into the trash bin and reducing the amount of trash in the
streets and public spaces, but also, making a tedious task into a fun one that
appeals to everybody.
Our project consists of a regular trash bin, integrated with a couple of infrared diodes and phototransistors, which will serve as the sensors that send a signal whenever something is thrown into the bin.
This sensors are connected to an Arduino R3, which will receive the signal,and using the instructions programmed into it, it will
send a series of pulses with different frequencies to the Buzzer, who will
reproduce these pulses forming a melody.
Arduino will receive the signal from any of the sensors and will increase the
value of the 7-segment display, simulating a score board.
the four sensors are activated at the same time and last two cycles activated
(15 seconds), this will mean that the bin is full, and a signal will be sent to the main computer, indicating
that this particular bin is ready to be emptied.
The components used in this prototype are:
- Trash Bin
- Arduino R3 (2)
- Infrared Diode (4)
- Phototransistor (4)
- Resistors 180Ω, 220Ω, 10KΩ (12)
- 7-segment Display
- 5V Power Supply
step was to create our program, we use an Arduino R3.
After, we made tests with the infrared diodes and phototransistors in order to
check if they were functioning correctly.
three parts were integrated: Arduino, Audio System (Buzzer) and Sensors. There was a test, and it was working correctly.
With all the electronic part working correctly, we started developing the physical component of the prototype: the trash bin.
After building a base for the bin, where all the electronic components will be stored, we positioned the sensors inside the bin, and connected them to our printed protoboard. Finally, we changed all the resistances and cable from our protoboard, into the printed protoboard, to improve the design of our prototype.
Take a look at what EcoFun is working on. We hope you like it!
