![]() If wiring is not the issue here, you’ll need to check the DAC and make sure its value is not 0 (or any value close to it).If wiring is not the issue here, you’ll need to check to make sure if you lubricated the bearings or if there are any dirt or dust particles trapped inside.If you don’t wire it correctly, you’ll see issues like: The biggest issue you’ll encounter when working with servo motors is improper wiring.Servo motors can rotate up to 180 degrees and to a specific position.You’ve made it to the end of this article, so here are the main takeaway points you’ll need to keep in mind: If that’s not the problem, you’ll need to check the bearing to make sure it’s properly lubricated or ensure that there are no dust or dirt particles inside your servo motor. Solution: You’ll first need to check the wiring and make sure your servo motor is properly grounded. You’ll need to act fast and locate the source of the problem before the components causing these odors and smoke get electrically damaged. If you take a whiff and notice a strong burning odor, then it’s likely your servo motor (or other components) are burning. You can either fix the motor itself or replace it.Īnother issue you may encounter is smoke or an odd smell emitting from the servo motor itself. If you find your DAC value to be 0 or any value close to it, then that is the reason why your motor is not working. Most of the time, you’ll only need to check the DAC (or the Digitial Analog Converter). ![]() Otherwise, you’ll need to learn how to debug your code. Solution: Go to the “Incorrect Wiring” section to figure out how you should correctly wire a servo motor. This can be either due to your miswiring or errors in your code Sometimes, your servo motor may not be working when you want it to work. Otherwise, you’ll need to check if your servo motor is properly grounded and that it’s receiving the appropriate amount of power. Again, you can check the above section on how you can properly wire your servo motor. Solution: Most of the time, you can attribute this sound issue to electrical problems or improper wiring. However, if you do notice loud or obnoxious noise coming from your servo motors when they’re running, you definitely have a problem. They’ll be humming at a low noise level so you’ll unlikely be able to notice it. Understandably, servo motors are supposed to make noise when they’re running. The one with the red wire needs to be connected to power, the black wire needs to be connected to ground, and the remaining wire needs to be connected to a control pin so that you can control it. Solution: As I’ve mentioned before, the servo motor has 3 female headers. If your servo motor works even with your bad wiring and you ignore it, you will encounter other problems down the road such as electrically damaging your components. If you are having a problem with your servo motor, it is most likely due to the fact you’ve wired it to your breadboard and Arduino incorrectly. Common Problems (And Solutions) You May Encounter With Servo Motors It was great for steering RC (remote control) cars or RC planes’ flaps. Still, servo motors were initially created and designed for the remote control world. I would press 3 different pushbuttons on the breadboard to make the servo motor rotate to a specific position and indicate my mood (i.e. Another project I’ve used it for was a mood indicator. As I’ve mentioned previously, I’ve used it in a Knock Lock project where the servo motor acted as a key. You can use servo motors for many different kinds of projects. I’ve used a servomotor in my Knock Lock project where the servomotor would turn and “unlock” once I gave it the proper “password”. It contains useful pin tips and a cool way to test them to make sure they’re working properly! I talk about pins here a lot, so if you want to learn more about them (like digital and analog pins), go check out my in-depth Arduino pin guide. For the control pin, you can just pick a random digital pin on your Arduino board. Normally, the red wire connects to power, the black wire connects to ground, and the remaining wire (mine is white) connects to the control pin. To use this type of servo motor, you need to connect one female header to power, another one to ground, and the final one to a control pin. ![]() For example, a light switch is digital because it can only do 2 things: turn your light switch on or off.įor connections, it has 3 female headers (which are just holes), which means you need male headers (which are actual metal pins) to connect it to the Arduino. Your Arduino sends electric pulses to it, which tells the motor what position it should be in, and these signals can either be analog or digital.Īnalog means that you can have more than 2 values while digital means that you can only hold 2 values.
