Other Sensors

Are there any other sensors I can connect to the vex, apart from those supplied by vex robotics?

There are no other “Plug-&-Play” sensors available at this time. You should be able to connect most any +5V sensor to the Vex Controller. Some sensors only have 2 output states, a High (+5v) or a Low (0v), which can be read by any Digital Input. Some sensors have a variable output that ranges from 0-5 volts which can be read from any Analog Input. You may need to provide the sensor with power and ground which are available on the Analog / Digital Connector.

I am trying to use a non-vex sensor and “disguise” it as a light sensor by putting it through a 10 bit Analog to Digital Converter, and hooking it up to the microcontroller. (The sensor has a 0-5 volt output.)

  1. Will this work?
  2. Do I need ADCs with a 0-5 input range?
  3. If so, where would I find one (I couldn’t find any)?

This forum is for Vex products but, many Non-Vex sensors can be connected directly to the Vex Controller. We provide specifications of the Vex Controller. When using non-Vex parts, you must determined whether the part can be interfaced with the Vex Controller. Not sure what you are trying but, a sensor with a 0-5 volt output should be able to connect directly to an Analog Input on the Vex Controller.

Do you have schematics on infra-red sensors that are compatible with the micro-controller?

** No. We provide specifications of the Vex Controller. When using non-Vex parts, you must determined whether the part can be interfaced with the Vex Controller. All Vex Schematics are proprietary and will not be released. **
