Hey friends, I am abit of confuse in the working principle of IR sensor.
I know that the transmitter will always give out infrared light and a receiver is connected near to the transmitter. So when a white line/white paper is put on top of the transmitter and receiver sensor, the transmitted ray will be reflected to the receiver. So, what next ? The receiver get the infrared ray then what it does next ? Provide 5V output ?
