Why a Prototype?
Building a shield entails soldering components to the PCB, which leaves limited room for testing, measuring and experimenting with the different components.
It is recommended to start creating a prototype. Connect with jumper wires the different componentes and verify that each sensor works. Once you get a running prototype, you can go to the next level soldering components to the PCB.
Prototype BoM
On top of the materials identified in Fenix BoM, for prototyping you will need a prototyping breadboard and M/M Jumper wires.
Prototype Schema
You can build the prototype following the schema below.
Notes for Prototyping
- Linear actuator with feedback is represented by,
- DC Motor
- Rotary Potentiometer
- 12V battery and wiring are not represented. You can use a 220V/12V current adapter instead of a battery is recomended.
- Breaker at the +12V entry should be used for security (Max. 5A recommended for testing).
- Arduino is powered by USB connection to laptop, not represented.
- DC Motor controller wired version represented, however the shield version is still recommended.
