QTRX-MD-05A Reflectance Sensor Array: 5-Channel, 8mm Pitch, Analog Output, Low Current Category_Arduino/Arduino you can get the SMT-only

you can get the SMT-only version and install a stackable 2×20-pin female header

such as your microcontroller

This common anode bar graph is perfect for projects requiring display meters with higher accuracy for reading a power charge

the indicator keeps slowly blinking when playing music

put on the snow or Christmas tree for it at Christmas

It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage. In general, the closer the object, the higher the contrast between light and dark readings, but high
