Today we are going to make a colour sorting machine using arduino and TCS 3200. The colour sorting machine Project is very unique and useful project. So we are going to share all the detail about this project how does it work and how can we made it. If you want to learn or make this colour sorting machine project you need to read full article because we are sharing all the details here. Such as code circuit diagram and each and every steps to make. The colour sorting machine Project is very famous product in the industrial purposes. So we are going to make this project with the help of wooden material and mechanical tools and materials.
There are many there are many projects using colour sensor. But this time we are making a colour sorting machine to differentiate the material like we are differentiating the different colour boxes using colour sensor in this machine having a conveyor belt which carry all the boxes and the conveyor belt also attached a colour sensor.
Which continuously object and its colour so according to the colour belt conve y or carry the product to the end of the machine where machine attached with container so that right colour parcel will be entertained by the right container. Such as if the parcel is blue colour the parcel will be collected by the blue colour container. So the sensor works on this principle.
There are three blocks in this project first is power supply and PCB block second is conveyor belt and the third is container.
Power supply and PC blocks
This is the first block of this project there we have attached power supply of 12 volt and 5 ampere and a circuit board which we have made for this project. In this circuit board where using arduino Nano stepper driver a4988 and bug converter which are using to step down the voltage. And a MOSFET tip 122 which will be control the DC motor. On-Off switch.
PCB control board block were using a 12 volt 5 ampere power supply which is the regulated power supply which give us DC voltage and from this power supply output we have connect the stepper driver stepper motor and DC motor because all these things required 12 voltage now from the step down voltage which we are getting from the bug converter we have to connect sensors like where using all these things will work on 5 voltage so we can get 5 voltage from this work converter
Conveyor Belt Block
Conveyor Belt block in The colour sorting machine Project is made by the totally mechanical structure. Hindi conveyor belt block there is a DC motor which is responsible for rotating the conveyor belt conveyor belt is set up on two iron rod which are connected with the ball bearing on the both ends. When the DC motor get power than the motor start to rotate and also it rotate the iron rod which are connected through the conveyor belt.
There were using a height of motor with low RPM nearly 30 RPM nearly 60 RPM. The motor is gear motor which have more talk and less speed so that it can easily rotate the police and conveyor belt there we have made a mechanical structure which can easily control the conveyor belt by using a DC gear motor so we have shared all the detail how can we made this conveyor belt with the help of wooden wearing and mechanical structure also we have made a full video tutorial on YouTube where you can get all the details and all the steps which can help you to make this project by yourself.
Container Block.
In this container block we have a container with four different container inside it so V named all the container differently as colours first is red then green then yellow and then Blue. This big container is connected over a stepper motor which is control by the arduino and there is IR sensor which can help us to get the initial position of the container mounted over a stepper motor will decide to rotate for different colour boxes. For example if there is a box of blue colour then the stepper motor rotate a certain degree which are associated with the blue colour block. Green yellow and red.

PCB Boards
Arduino Nano:- Arduino Nano is a microcontroller development board having atmega16 controller. Arduino have 13 digital input output pins, 8 Analog Pins and pwm pins. it supports Serial communication, I2C Communication, SPI communication protocols. In this project Arduino nano working as a brain which getting input from the TCS 3200 and IR sensor and operate dc motor, Stepper motor on it’s output ports.
Stepper Driver A4988:- Stepper Driver a4988 is used to control the stepper motor. without the a4988 the stepper motor can’t work. Stepper motor can’t run directly on the Arduino. so, we need to use this driver.
Buck Converter:- Buck converter or step down voltage device is help to maintain variable voltage as per our requirement. there is a potentiometer which can control the voltage when we rotate the potentiometer.there is switching of input voltage in buck converter through the inductor. which store the power as magnetic field.then it release the energy to the load.
TIP122 :- TIP 122 is a MOSFET which can control the DC current. the mosfet is work as a switch here. when external voltage applied on the gate terninal then the source and drain start conducting the electricity. we use this mosfet as a switch to control the DC motor in this colour sorting machine Project.
IR Sensor :- IR sensor also known as the infrared sensor. which transmit the Infrared light and receive by the receiver. if there is an object infront of the sensor then the receiver get the tranmistted light and turn the signal on. so it helps in this project to find the initial position of stepper motor.
Nema 17 stepper motor:- Nema 17 stepper motor have high precision and high torque in this range of stepper motor thats why we are using this motor in this project. Stepper motor always rotate in steps that’s why they are called as stepper motors.
TCS3200:- TCS3200 colour sensor is most knowing colous sensor in the sensor industry. we have made a alot of project on this sensor also our this Colour sorting machine project we are using tcs3200 sensor. There are 4 led which transmiot the white light to the object. object may have any colour. for example we have a red colour object. The colour object that wavelenghth. and the receiver doesn’t receive the colour spectrum by this The colour sorting machine Project the sensor get to know the colour of the object.
Now, we need a circuit diagram.
