Hello,
I am new to PCB design and I want to know the 2 resistor value for ITR8307 reflectance sensor? I want to hook the sensor up to a Blue Pill ADC Pin. Can anyone Help?
Are you connecting the LED to 5V, 3.3V or a Blue pill output pin?
What are you trying to detect?
That information is on the data sheet https://www.mouser.com/datasheet/2/143/ITR8307-L24-TR8-8635.pdf . However it does not tell me what voltages you are using or how it is connected in your circuit. There are possibly thousands of combinations.
5v from a voltage regulator
Check page 7 of the data sheet then you need to determine if you want an active high or low output and wire the output accordingly.
