#Sonar vs slate vcc how to
Our first example demonstrates how to move a servo motor using the SparkFun Servo Trigger. Servo Control with the SparkFun Servo Trigger This is particularly important when you are sending PWM values from a microcontroller or single board computer like we demonstrate in the Arduino and Python sections. Be sure to check your servo's specifications for the pulse range to avoid damaging the motor and gearbox. This is usually between 1 and 2 ms but can vary between manufacturers and servo types. The primary thing to remember here is your servo's control signal pulse duration/width range.
For a more thorough explanation of a how a servo control signal works, check out this section of our Hobby Servo tutorial. We're only going to cover the control signal range for this tutorial. The last concept we want to revisit is a servo's control signal range.
Usually, you can look at the stall current (if listed) in your servo's datasheet to determine the max current draw of your servo motor. Again, the datasheet for your servo will have some helpful information to figure out the max current your servo may draw from your power supply. Also, ensure your power supply can supply enough current to drive the servo. Make sure the voltage provided by your power supply falls into the voltage range for your servo (commonly 4.8-6V but check the datasheet for your servo to be sure). Next, you need to select a power supply for your servo project.
