To decoder and then segment display Hi, I have connected the circuit as shown above. Opamp is used as a comparator The positive terminal of opamp is given fixed voltage of 2.5 V. The negative terminal is given a voltage divider biasing. When IR ray is incident on the sensor, its resistance is less than that of the resistor. Hence voltage above 2.5 V will be at the negative terminal, and output is 0 V. Opposite is the case when the beam is cut, and the output is app. 3.4 V I want to use this output voltage to give pulse to the IC(positive edge triggered) but I m not getting proper output(counter ic and display is working properly, problem is with the pulse input) Can u plz help me how to give pulse in this manner
