A new board for the 3Drag: there’s more than Sanguinololu using arduino

When we first released our 3D printer, we tried to use some parts that were already available and tested, in full respect of the open source philosophy. In particular, we decided to use the electronic card Sanguinololu. The “open” firmware we chose, the Marlin firmware by Erik van der Zalm, solved the biggest part of the computer interface issues. The Sanguinololu was great, but being innovators by vocation ...

Pololu Dual MC33926 Motor Driver Shield for Arduino

This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the ...

World’s Smallest Stepper Motor with Arduino and EasyDriver

This little wonder of electromechanical engineering came from inside a laser diode sled of an HP CT10L Bluray drive I’ve opened some time ago. The device on the picture consists of several parts, all easily fitting on a dime coin: a bipolar stepper motor with lead screw, a linear stage, a lens, and even an end position sensor (I’ve yet to make use of the sensor though). The entire assembly is only 14mm x 9m ...

Controllers and Sensors using arduino

Intro The Arduino microcontroller board is able to supply a current of 40mA from its output connections. These digital outputs are fixed at 5V “ON” or 0V “OFF”. This is adequate for working with LEDs but devices such as motors, solenoids, high brightness LEDs etc. may require much higher currents and voltages. To achieve this an interface in between the Arduino and the device can be made from locally source ...

Arduino + 2 Servos + Thumbstick (joystick) using arduino

In my other 2 Arduino tutorials I have help new users to play tones and making 2 servos move with a mouse. This time I will help you move the same 2 servos with a thumbstick. And again I have surf the internet to see If there are tutorials that clear to understand specially for the beginner Arduino user and, I have not found one. To move 2 servos with the thumbstick is way easier and painless than using the ...

Stepper Motor drive from Arduino

Stepper Motor drive from Arduino In this tutorial we will show you how to connect a bipolar stepper motor to an Arduino Uno board. The stepper motor we are using is the Sparkfun Stepper Motor but you can use any other 4-wire bipolar stepper motor. Because a stepper motor draws a higher current than the Arduino processor can handle we are going to use a Quad half H-Bridge chip to control the stepper motor. T ...

Adafruit Arduino Motor Shield Build

Overview The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features. The shield is T ...

Servo 360 rotation mod (Parallax)

In this instructurable I will expalin and show you how to make a Parallax servo rotate 360º. And againI have search the internet to see tutorials clear enough to make this posible with no luck. Don't get me wrong they are some how good but not clear. This mod will help you to use the mod servo for robots that need a fully 360º rotation servo. Also some of the pictures were taken from other instructurables a ...

DIY Mod an Omnibot 80’s Robot with Voice, Camera, Servos, Bluetooth

*Check back for more updates on this build :) So, have you heard of the Omnibot? Well! Any kid from the 80's will remember how amazing this robot was. For you young kids, this robot was released in the early 80's by Tomy. The robot was "programmable", in the sense that the actions were recorded to a casette tape. As you operated the robot over its remote control, the casette would record tones for each acti ...

DIY Arduino Stepper Motor Driver Board

This page will show you how to put together a simple stepper motor driver board that can be controlled with an Arduino. I built mine to use with my heliostat projects, but it could be used for other things too. Update: I no longer use this driver board with my sun tracking / heliostat system. Commercial driver boards have become so cheap that it is hardly even worth bothering to build it. Additionally, this ...
