![]() ![]() Using the Serial.print() function we will print the result on the serial monitor. Then using the “pulseIn()” function we will read the output frequency and put it into the variable “frequency”. For that purpose we will set the two control pins S2 and S3 to low logic level. In the loop section, we will start with reading the red filtered photodiodes. Here we also need to set the frequency-scaling, for this example I will set it to 20%, and start the serial communication for displaying the results in the Serial Monitor. In the setup section we need to define the four control pins as outputs and the sensor output as an Arduino input. TCS230 Color Sensor Source Codeĭescription: First we need to define the pins to which the sensor is connected and define a variable for reading the frequency.
