![]() ![]() There is a total of 4 combinations possible. Since these are 2 pins (S2 and S3) and each one can be HIGH or LOW, These determine the color that has been sensed. Probably, the most important of the 2 pins are S2 and S3. But to go a little more in depth, we give a few tables below on how exactly So now you know the functions that each pin has. Output pin gives the output frequency (of the color sensed)Ĭonnected to 5V or to a digital pin, the LEDs on the chip board will S2, these pins determine the color sensed by the sensor. S3, these pins determine the color sensed by the sensor. S0, these determine the scaling of the output frequency. S1, these determine the scaling of the output frequency. Is where you connect ground to in order to complete the electrical Is where you feed the positive voltage to power the chip. Since 2 of the pins are redundant, VCC and GND, the table shows a description of 8 pins. The pins of this chip are summarized in the table below. So this is how this sensor can differentiate between colors. So basically the light is converted into a frequency.Įach color has its own unique frequency. Then determines the color that was sensed. Which corresponds with the color of the light, produces a certain frequency. This current is then fed into a frequency converter. What this means is the sensor takes light and converts it into certain amount ofĬurrent. In this circuit, we will make a device that can detect between white, bliue, How to use one is very useful, especially in this robotic, autonomous day in age. So there's no shortage of devices that a color sensor can be used in. Other applications include strip reading, ambient light sensing and calibration, If you know you have a green towel and another person has a red towel, the robot Imagine if you have a robot that can tell the difference between a green towelĪnd a red towel. If a robot can differentiate colors, it has much The moreĬapabilities a robot has, the smarter it is. To be able to detect colors at places such as red stop signs and of course traffic lights,Īnother device that a color sensor can be integrated to is robotics. Vehicles are being developed that can run on their own, driverless cars, there has to be a way This sensor can detect and differentiate between the colors white, blue, green,Ī color sensor is actually a very useful device. ![]() The sensor we will use in this circuit is a TCS3200 color sensor. In this project, we are going to build a color sensor circuit with an Arduino microcontroller.Ī color sensor is a device that can detect and differentiate between certain primary colors. ![]()
