How Linear Actuators are Controlled by Relay Boards

Linear actuators are mechanical devices that transform energy to create straight line motions. A relay, on the other hand, is a switch whose operations are electrical. This article teaches users how linear actuators are controlled by relay boards. The only difference in relay boards is the number of relays they carry since all relays' action are the same.

To control two actuators in a MegaMoto control board, four relays are combined with the board. The relays on the board choose the direction while the board gives the actuators speed signals.
While creating an H-bridge for driving a motor at 10A for up to 30V, two relays can be used.
In the activation of an electromagnet, the input current is used by the relays. The work of the electromagnet is to pull the switch, one position to the next, allowing currents of a higher power on the relay's other side to flow. In this way, an Arduino control side (small power current) can be able to control an actuator control (a large power circuit).
The following are required for this project. One Arduino Uno, one relay board, one MegaMoto motor controller and M/F Jumper wires.
The first step is to wire the board basics. A GND pin is found on the relays on the control side. A Vcc pin follows the above, and then all the INx pins(1-8). For relays to hold active, a fair bit of p...
