Stepper motor control using arduino is a simple project where a bipolar stepper motor is controlled using arduino uno.

Circuit diagram arduino uno. Previously we have made a very simple metal detector without a microcontroller now we are building the metal detector using arduino. The processor has plenty of gpio analog inputs hardware uart spi and i2c timers and pwm galore just. The board is equipped with sets of digital and analog inputoutput io pins that may be interfaced to various expansion boards shields and other circuits. The arduino uno is an open source microcontroller board based on the microchip atmega328p microcontroller and developed by arduinocc. In the earlier lessons we wrote our first programs and built our first circuit. Metal detector is a security device which is used for detecting metals which can be harmful at various places like airports shopping malls cinemas etc. Stepper motor is a type of brushless dc motor that converts electrical pulses into distinct mechanical movements ie. Power supply analog and digital pins and icsp. The board has 14 digital pins 6 analog pins and. The shaft of a stepper motor rotates in discrete steps. The guide also discusses different communication protocols used by the arduino and a detailed diagram of the arduino uno board. The circuit diagram below is a concept that should work with any microprocessor or a specialized driver ic that is able to produce the correct commutation sequence. Adafruit industries unique fun diy electronics and kits adafruit metro 328 fully assembled arduino ide compatible atmega328 id. This robotic arm can be controlled by four potentiometers attached to it each one used to control a servo motor. The arduino uno pinout guide includes information you need about the different pins of the arduino uno microcontroller and their uses.

The first two red and black connect to the two long vertical rows on the side of the breadboard to provide access to the 5 volt supply and ground. Image developed using fritzing. At this time you should be getting comfortable with how the breadboard works and how to work with variables and digitalwrite commands in the arduino ide integrated development environment. Open source electronic prototyping platform enabling users to create interactive electronic objects. 50 we sure love the atmega328 here at adafruit and we use them a lot for our own projects. For more circuit examples see the fritzing project page.
