Hey someone out there, I am new into PIC programming and hobby designs, and i am currently trying to configure an infrared reflective sensor "HOA0709" to detect a black line. But i cant get it to work, the photodiode or should i say the transmitter side can switch on with 50mA, i have calculated the resistor before the IRED of 100 ohm but i cant get the sensor to work even just light the LED. it cant even switch the darlington transistor on as a result.
May i please have help on this, i doing a line following robot with multiple input sensors. thank you.
