Today, my partner and I were testing the photo-transistor on a PCB. We first had to find the right resistor for our flame sensor to work properly. After trial and error, we decided to use a 22kOhm resistor that gave an output voltage of about 2 Volts. We also measured the range voltage at about 1 meter away. These values, the one meter range and the 10 inch close range, will be used later in the programming for the VEX and photo-transistor interface.
In the meantime, I continued programming for the Ultrasonic-sensor. This sensor lets the robot sense objects that may be in its' path.
