Introduction Contents [show] In this tutorial, you’ll learn how to control a DC motor’s direction using an H-bridge. To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit. There are many different models and […]

REQUIREMENTS: 1. Microcontroller (AtMega 16) 2. A Brushless DC motor (BLDC) 3. An Electronic Speed Controller (ESC) 4. Power source to drive the motor (LiPo battery) DESCRIPTION: Brushless motors have much more satisfying results as compared to brushed motors. The basic difference between them is that in a brushless motor, the rotor itself contains the

Microcontrollers are good when it comes to brain, but to do anything in real world they need muscles too ! Their muscles are electromechanical actuators like motors. Their are several types of motor available to do various type of motion. The simplest of them are DC motors. They can generate rotary motion and when wheels

Stepper motor can be termed as digital motor because it operates on pulses. Unlike AC or DC motor that rotates continuously, stepper motor rotates in steps. It rotates in number of steps as per applied number of pulses. Stepper motor is used in many applications like: . Robotic application – to move robotic arm to

In many of the applications it is required to alter the direction of DC motor instantly. Like in washing machine, mixer, drilling machine winding – rewinding machine etc. Changing the direction of DC motor using joystick is most suitable and handy method. Joystick Control for DC motor is mostly used in different Robotic applications like

Servo motors find huge applications in industries in the field of automation, control & robotics. The servo motors are well known for their precise control and work on the principle of servo mechanism. The servo motors can be made to run at precise angle using PWM. The PWM (pulse width modulation) is the basic working

Background We designed and implemented an automated, portable bird-trapping mechanism, along with an associated system which is scalable Every year between early May and mid-June large amounts of tree swallows migrate to Ithaca, NY area to mate. The study of these birds invariably require a large number of specimens to be captured for purposes such

Introduction The BalanceBot is a singular axis self balancing robot that is capable of adjusting itself to changes in weight and position. We developed the Balance Bot (BB or B2) from a single servo and a single accelerometer. This was very much a proof of concept to show the capabilities of the ATMega644 in doing
