There are two ways to connect Vernier sensors to Arduino. You can plug any standard Vernier sensor with a BTA or BTD connector directly into a Vernier Arduino Interface Shield or you make your own wired connections with a breadboard and one or more Vernier Protoboard Adapters.
The method you choose will depend on the complexity of your project. Be sure to use an Arduino board that operates at 5 volts; standard Vernier sensors will not work on 3.3-volt Arduino boards at this time.
Wiring a Single Analog Protoboard Adapter
Wiring a Second Analog Protoboard Adapter
A second Analog Protoboard Adapter allows you to use two Vernier analog sensors at once with your Arduino.
Wiring a Single Digital Protoboard Adapter
Wiring a Second Digital Protoboard Adapter
A second Digital Protoboard Adapter allows you to use two Vernier digital sensors at once or a digital sensor in conjunction with the Vernier Digital Control Unit (DCU) or the Vernier DCU by itself. Be aware that the VernierLib commands assume the sensor is plugged into the first adapter and the DCU is plugged into the second adapter.
