Controlling a Linear Actuator with an Arduino and Relay We have made for you an easy to follow step by step guide on how to control your Linear Actuator. If you have any questions feel free to get in touch with us and we will be more than happy to answer them. Bridging the Power Gap : Arduinos operate at low voltage (typically 5V) and can't handle the higher currents most linear actuators require. Relays act as a bridge. They're controlled by the low-power signal from your Arduino, but allow the higher current needed by the actuator to flow through separate power connections. Flipping the Switch (Voltage Polarity) : Relays can be used to flip the polarity of the voltage delivered to the actuator. This clever trick is key to controlling its direction. By manipulating the positive and negative connections, you can tell the actuator to extend or retract. Stopping Power: Relays offer more than just basic on/off control. In its default state, the relay keeps both connections open, effectively stopping the actuator like a switch turned off. However, relays can also be used for "controlled stopping" by selectively connecting the positive or negative terminal with your Arduino signal. This allows for a more precise hold position and opens doors for advanced techniques. Applications of Relays in Linear Actuator Control While linear actuators offer incredible force and movement, controlling them directly with a microcontroller like an Arduino can be tricky. That's where relays come in. They act as intermediaries, allowing your low-power control signal to safely manage the higher current needed by the actuator. But what does this translate to in real-world applications? Let's explore some exciting ways relays and linear actuators work together: Simplifying Automation: Smart Furniture : Imagine a sit-stand desk that automatically adjusts to your preferred height at the touch of a button. Relays make this possible by allowing your microcontroller to control a linear actuator tha
