1. ELEC Freaks www elecfreaks com Color Sensor Module User Guide Color Sensor Module Introduction The Color sensor module base on TCS3200 which is a programmable color light to frequency converter it could filter RGB data from source light and convert it to a square wave 50 duty cycle with frequency directly proportional to light intensity irradiance The full scale output frequency can be scaled by one of three preset values via two control input pins SO S1 Selectable Options 2 20 100 frequency and pin S2 S3 control the filter of RGB Digital inputs and digital output allow interface to a microcontroller or other logic circuitry directly Output enable OE places the output in the high impedance state for multiple unit sharing of a microcontroller input line At last user can calculate the color of the light by RGB values ELEC Freaks www elecfreaks com Hardware and Software Preparation Hardware OP Jumper Wire 2 Color Sensor Module 3 Arduino UNO 4 Paper with 4 colors J 1P Jumper Wire x3 6 Mini USB Cable Software Arduino IDE 1 0 X Photoshop color picker Step1 Upload the Code SES e Tee TS UNO s Freaduino ELEC Freaks www elecfreaks com Connect the Arduino UNO to PC with the Mini USB Cable Open the Arduino IDE1 0 X and download code from our WIKI If your IDE do not have TimerOne Library please Download it from here Choose the corresp2. hen the mark 2 is the scale factor Then use the scale factor for adjusting the RGB value to 255 as Mark 3 ELEC Freaks www elecfreaks com Step 3 Test colors with RGB value 1 The normal measurement distance is 0 2cm so we put the color sensor module on the paper another part 2 Open the Serial Monitor and now you have got the object s RGB value like 13 14 14 which means you have got the object color H jiso E lL 4 D ae s a 0 cef Chp pegis cfs C fis M 83 CB fi Y 83 oddete K 73 RA Web gie 3 Open photoshop color picker and the RGB value 13 14 14 means it is black
