We’ll use four buttons to move the servos in four distinct directions: up, down, left, right.įirst, we’ll import the Servo library and define our buttons as globals. When the button is released, the servo will stop. That means, when the button is pressed, the servo will move. We want to use the buttons as momentary switches. Now, we’re going to look at programming pan-tilt servos using four buttons.

I’ve used up to 50-millisecond delays in some projects!Ĭlick here to download the full Arduino Potentiometer sketch (.ino) Code for Pan-Tilt Servos controlled by Buttons You can test out this number to see what works best for your application. I recommend adding in at least a 15-millisecond delay. For example, if our tilt servo is named “tilt”, we can tell the servo to move to the mapped position using the following code:įinally, give the servo enough time to get into position. When you’re done, you can command your servo into position by using the myservo.write(pos) method. Then, repeat this process for the second potentiometer. If your servo has a different range of rotation, be sure to map your potentiometer reading to match this spec! Therefore, we can use the mapped value to command our servo into a position. Most hobby servos are 0-180 degrees of rotation. We’ll need to map this value to the range of our servo (in degrees). This will be reading from 0-1023 because we have a 10-bit ADC on the Arduino. Next, you’ll want to read the value of the first potentiometer using analogRead(pin) and store that into a variable. I’ll be following these guidelines loosely, so some prior Arduino programming experience is expected. If these concepts are foreign to you, please check out my article on Four Steps to Writing Any Arduino Program.

Then, initialize the Serial Monitor within the method. Next, create some constant global variables to store the potentiometer pins.

Code for Pan-Tilt Servos controlled by Potentiometersįirst, import the Servo library for this project. We will be using the Arduino IDE for our code development. Realistically, once you have one control pattern written, the others are very easy to develop.

In this guide, I will show you how to program pan-tilt servos using potentiometers, buttons, and a joystick. Go ahead and pick one (or all) of these options, wire up the circuit(s), and then come back to this article to learn how to program it. This would be another great option! (And would combine the programming logic from the joystick and button sections.) They include both a joystick and a set of four buttons. There are also Joystick Shields that you can get for Arduino. If you want a user experience similar to a video game controller, this is the option I’d pick. Lastly, we can program pan-tilt servos using a joystick. This is just a starting point for getting it wired up! Pan-Tilt Wiring Diagram using a Joystick We will assign functionality to the buttons in the code, so this can be configured however you like. Here’s a diagram for pan-tilt using buttons: When the user releases the button, the servo will stop in its current position. When the user presses and holds a button, the servo will move accordingly. Pan-Tilt Wiring Diagram using ButtonsĪlso, you may opt to control the movements using four buttons. Furthermore, the servo connections will stay the same throughout this guide. The capacitors are there to reduce the amount of noise on this line. The servos are powered by a separate source. You’ll notice a couple of capacitors (bottom right corner) connected to the servos.

The first wiring diagram uses two potentiometers: one for pan and one for tilt. Without further delay, let’s get started! Pan-Tilt Wiring Diagram using Potentiometers

Would it be easier for the user to push a button, rotate a dial, or jog a joystick? When deciding on which circuit to build, I recommend thinking about how the user will use this system. The programming methodology will be similar to all of these examples. There are three options to control the pan-tilt movement: potentiometers, buttons, or a joystick. The first thing we’ll do is create our circuit.

The goal is to have (wired) manual control in all directions (pan: left/right and tilt: up/down). This tutorial will show you how to program pan-tilt servos using buttons and potentiometers. So, if you haven’t already built yours, I recommend checking that out first. In my last tutorial, I showed you how to build the pan-tilt servo assembly.
