Both IR sensors are connected to the interrupt pin of Arduino, and they detect the falling wave. The purpose of using interrupt is that, it improves the efficiency of system. A LCD is connected to Arduino and measured speed is shown on LCD. When car moves in front of the first sensor, ...
This should not happen, except for MCUs with a nominal internal reference voltage different from 1100 mV (e.g., ATtiny26, ATmega8, ATmega16, ATmega32, and ATmega8535). It may happen, if you do not connect AVcc and Vcc (e.g., on a ATtinyX61 and ATtinyX7). The most likely reason is...
arduino. If digital pin 4 is held high, the output will be in centimeters and if the digital pin 4 is held low, the output will be in inches. Digit driver transistor Q1, Q2 and Q3 of the arduino are interfaced to digital pins 1, 2 and 3 of the arduino. Multiplexed segments a to...
