Robo Waste Collector | Smart Bin by Arduino|IGNITERS MINDS

The threat of waste to the environment health and safety is huge.

Hopefully this project will work to keep us from littering everywhere. Garbage increases the risk of various diseases. Besides, it spoils the beauty of area.

’bout Updated work-

Public waste bins are filling up faster than ever and inevitably many of the bins end up overflowing before collected,causing not only cluteered streets and bad odors but also negative health and environment health and environmental impacts. Some of the garbage will not giving off foul smell.The rotting garbage will become a breeding ground for disease causing organisms such as cockroaches,flies and mosquitos.With this in mind,we’ve been able to make ordinary buckets less difficult to use.

Here we will make a Smart bucket by using arduino,servo motor & ultrasonic sensor.We will update the common bucket and make it environment friendly.In this procedure, the lid of the bin stays closed, it will open the lid automatically after detection the dirty obstacles. A pot like this is needed first to get rid of the dirt.

1. Power:

Vin, 3.3V, 5V, GND Vin: Input voltage to Arduino when using an external power source. 5V: Regulated power supply used to power microcontroller and other components on the board. 3.3V: 3.3V supply generated by on-board voltage regulator. Maximum current draw is 50mA. GND: ground pins. 2. Reset : Reset Resets the microcontroller. 3.Analog Pins A0 – A5 Used to provide analog input in the range of 0-5V 4.Input/Output Pins Digital Pins 0 - 13 Can be used as input or output pins. 5.Serial 0(Rx), 1(Tx) Used to receive and transmit TTL serial data. 6.External Interrupts : 2, 3 To trigger an interrupt. 7.PWM : 3, 5, 6, 9, 11 Provides 8-bit PWM output. 8.SPI: 10 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK) Used for SPI communication. 9.inbuilt LED : 13 To turn on the inbuilt LED. 10.TWI : A4 (SDA), A5 (SCA) Used for TWI communication. 11.AREF : AREF To provide reference voltage for input voltage.

We made the lid by cutting to the size of this bucket using a CNC machine.Another Two important element is ultrasonic sensor to detect any kind of dirt and servo works for turn up the lid. Now, let me take you through the actual setup and build process of the Smart Dustbin using Arduino. First, I will start with the mechanism to open the lid. I have used a Servo Motor for this purpose.In order to open the lid, it must be placed near the hinge where the lid is connected to the main bucket From the following image, you can see that I have fixed the servo motor on the (bucket lid).Also, make sure that the lifting arm(strong thread) is parallel to ground under closed lid condition.

Once the servo is in position, you can move onto the Ultrasonic Sensor. Make two holes corresponding to the Ultrasonic Sensor on the lid of the dustbin, as shown in the following image.WARNING: You have to use a sharp object with a lot of force to make these holes. Be careful.Now, from the inside, place the Ultrasonic Sensor through the holes and fix its position with the help of glue.

The Diagram is telling you all things About Arduino's pinpoint and how to connect it.The final step in the build process is to make the necessary connections using long connecting wires as per the circuit diagram and securing these wires so that they don’t hang around.All the wires from both the components i.e. Ultrasonic Sensor and Servo Motor are connected to respective pins of Arduino. This finishes up the build process of the Smart Dustbin.

After setting up the Smart bin and making all the necessary connections, upload the code to Arduino and provide 5V power supply to the circuit.Once the system is powered ON, Arduino keeps monitoring for any dirty object near the Ultrasonic Sensor.then Arduino calculates its distance and if it lessthan a certain predefiined value,(we were defind 3 cm) Arduino will activate the Servo Motor and with the support of the lifting arm,it will list the lid open. After certain time(we set up 5 sec sleep time), the lid is automatically closed.

A small Bucket

Here's a plans to update it.If someone throws out the dirt.It will grab the dirt with his robotic hand and throw it inside.The Alarm will sound when it is full.
