Question

Provide a circuit diagram and explanation for controlling a linear actuator using an Arduino. How can you provide more power to the motor than Arduino can handle?

Answer 1

The parts required for the project setup are Arduino UNO, progressive automation PA-14-6-50, 12V 5A power supply, female power plug, small flat head screwdriver, pololu VNH5019 motor driver rated at 12v5a and SPDT relays. These are easily available, and are part of a setup that is easy to build and comes up with a powerful automated system.

In reference to the linear actuator circuit assembly, the board comes with male headers and screw terminals unattached. This can be attached through a soldering iron. There are four holes on the board which are considerably large. These are for the wires which are not the right spacing, considering the screw terminals. However, there are a pair of smaller holes which are the right fit.. The female power plug is then screwed onto the GND/VIN on the VNH5019. This allows easy plugging and unplugging the power supply. It is also possible to put switch to facilitate for an E-stop.

Arduino is powered via a USB. It is also possible to have a 12v5a power as well as the USB. It is important to note that the Arduino can handle 12V power, so one can get the 12v6a power supply and still power everything using the USB
