Auto-ID for Digital (BTD) Sensors

This is simple sketch showing how AutoID can be used with Vernier digital (BTD) sensors. Most Vernier BTD sensors have a fixed resistor which is used to identify the type of sensor. After the sensor is identified the sketch displays the sensor name.

This sketch works with the SparkFun Vernier Interface Shield. To use this sketch with a system you wire yourself with one BTD adapter on a on a breadboard, the AutoID pin of the BTD adapter (pin 3) needs to be connected to pin A5 of the Arduino.

AutoID with multiple sensors: To make the AutoID system work for more than one adapter requires more complex electronics. The SparkFun Vernier Interface Shield contains a multiplexer and it can handle autoID on two BTA and two BTD sensors in one sketch.

This is simple sketch showing how AutoID can be used with Vernier digital (BTD) sensors. Most Vernier BTD sensors have a fixed resistor which is used to identify the type of sensor. After the sensor is identified the sketch displays the sensor name.

This sketch works with the SparkFun Vernier Interface Shield or a BTD socket wired via a breadboard.

AutoID with multiple sensors will work with the SparkFun Vernier Interface Shield, but to make the AutoID system work for more than one BTD connector, using one sketch, requires added electronics.
