Switching Voltage For Sharp Sensor
Hi @Athena, I have a question about powering the Sharp IR Distance Measuring Sensor #GP2Y0A02YK0F, which I am using in my rover project. I've been experimenting with this sensor, and it has worked very well for object detection when powered with 5V DC. During my tests, I found that for specific tasks, the sensor needs to detect a reflector instead...
