74HC161 is a synchronous presettable binary counter with an internal look-head carry

Gain Adjustment Potentiometer

High impedance differential inputs

all the segment outputs are HIGH independent of all other input conditions

Line Tracker Sensor MAX6675 then the output of theIntroduction: TCRT5000 sensors continuously emit infrared infrared emitting diodes, infrared rays emitted when not being reflected back or reflected back but the strength is not big enough, the phototransistor has been in a shutdown state, then the output modules is high, indicating diode remains off state; when the object appeared to be detected within the detection range of the infrared is reflected back and the intensity is large enough, the
