arduino颜色识别

本帖最后由 gada888 于 2018-11-25 22:22 编辑

做一个简单的颜色识别，不用那么多的连线，对着arduno直插，当颜色模块对着一个物体的时候，串口就会读出相应的颜色用到的硬件只有TCS3200.和arduino UNO。



TCS3200的电源输入电压是2.5v-5.5V
S0和S1是选频率的。两个都选HIGH

连线是
• S0 ------ D3 Arduino
• S1 ------ D4 Arduino
• S2 ------ D5 Arduino
• S3 ------ D6 Arduino
• OUT ---- D7 Arduino
Vdd----VCC arduino
GND---GND arduino

因出差，不方便放视频。
