Stepper Motors

Stepper motors are not smooth - they move in "steps". Different motors have a different number of steps to make one complete rotation. You use software to step the motor forward or backward at different speeds. There are two kinds of stepper motor bipolar and unipolar - Unipolar will have five or six cables coming from them. Bipolar will always have four. They function the same but you need different chips ...

Sweep

Sweeps the shaft of a RC servo motor back and forth across 180 degrees. This example makes use of the Arduino servo library. Hardware Required Arduino Board (1) Servo Motor hook-up wire Circuit Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. The ground wire is typically black or brown and should be connect ...

Hack a TowerPro Micro Servo to Spin 360 / Continuous Rotation

Hey guys! Since I've got my servos, I've had two that I set aside for hacking. So, coming to my favorite website for help, I was sorely disappointed when I couldn't seem to find any instructables on how to mod a micro servo. After viewing a few, I went to my workbench and got to work. I was very surprised when I opened up my micro servo and found it to be slightly different then the bigger servos. So, I dec ...

Using Servo Motors with Arduino

In this instructable, I am going to show you what a servo motor is, how to use it, and ideas for starting projects using it. I used arduino to control my servo, I added how to use a 555 in some of the later steps. Step 1: What is a Servo motor If you are like me, then you knew very little about servo motors, and how to use them, so we should start from the beginning. A Servo motor uses pulse width modulatio ...

Using Servos with Arduino made easy !

Servomotors or simply servos are essential components of a robot which convert electrical energy into mechanical energy.They are widely used in the field of RC hobby and robotics. But unlike simple geared motors , these servos are made by integrating a geared motor with a position feedback circuit which allows us to control the rotation of the shaft precisely. To drive a servo , we need a controller which p ...

Access control with Arduino plus Keypad 4×4 plus Servo

Hi guys, I bring a new instructable for arduino, the control access with password, 4x4 keypad and a servo. We will use the Password and Keypad librarie for arduino, besides using the servo library, but this project can also be modified by changing the servo, a motor reley or motor stepper, or any other ideas ... This project can be used in different cases, for doors, Servo action, etc..   Step 2: Prepa ...

Controlling Hand Drill with Roboduino using Arduino

This will explain how we re-purposed a hand drill to re-spool solder using a roboduino (arduino compatible), two servos, and a DIY encoder.  While one could use TRIACs to play with the AC power going into the drill, just using a servo to control the throttle is simple and avoids the pesky high voltage. Hand drills are pretty strong, hopefully this instructable will help others integrate it into other projec ...

Control Servo with Light using Arduino

Hello! In this Instructable i will teach you how to control a servo using a Photocell. This is very simple and good for beginners. Step 1: Materials 1 x Photocell 1 x 10k Resistor 1 x Arduino 1x Breadboard 1x Servo and some jumpers Step 2: Wiring it up Wire everything following the schematic below. Step 3: The Code The Code is very simple: #include <Servo.h> Servo myservo; int val; void setup() { myse ...

Simple 2-way motor control for the arduino

When I say simple, I don't mean use a speed control. But control the motor directly without any external circuitry. Here's how: How this came about: I recently was working on an instructable about charlieplexing with an arduino. And I was wondering if the same principle would work with motors to some extent. So I came up with the idea that if you used a motor instead of an led you could have 2-way cont ...

Serial Servo Controller with Arduino

I'm going to show you how to use your Arduino to control up to 12 servos at once with minimal jitter.  Using a simple serial interface you can control the position of up to 12 servo channels.  Up to 10 snapshot positions can be saved and played back at any time.  Start up values for each servo can be saved as well. There are two major parts to the application.  The first part I will discuss is the firmware ...

Compact 3-in-1 Stripboard DIYduino with Integrated Sensor and L298N Motor Shield

I am presenting a compact design of a stripboard Arduino board (DIYduino) that includes a 2A motor driver and has additionally the functionality of a sensor shield. The 2-channel version cost approximately $29.43 and is more affordable compared to $39.00 for a commercially available system consisting of an Arduino Uno, $21.50, a sensor shield, $8.50, and a motor shield, $9.00. The cost can be further reduce ...

Drive by wire go kart using Arduino

I just got a new go kart engine, i went from 6hp to 10hp. This new kohler engine I got I think was not built to put on a go kart, so I had some trouble finding a way to attach the gas petal. Well after a few days of not really figuring anything out, I remembered that I had gotten an arduino about a week ago, and maybe I could use this to help me out. Step 1: Power and safety circuit below is a diagram of ho ...
