I built a line follower with five QRD113 IR sensor(Analog) and Arduino UNO. I'm using LiPO 7.4v battery to power all my circuits. When at-least one of the sensor is in black line, I get some reading from my sensors properly, but when all the sensors are in white background, I don't get any reading from my sensors.
I checked using serial monitor. When all the sensors are in white, UNO doesn't read anything. Is it problem with the powe supply are some else?
