Controlling Servo Motor using Freeduino
Servo is a special type of motor which converts electric signals in to shaft positions. Servos can be broadly classified as Industrial servos and Hobby grade [[wysiwyg_imageupload::]]servos.Industrial servos are generally heavy duty high power AC or DC servos widely used for precise robotic arms.Hobby grade servos are widely used in RC Hobbies like RC Plane, Cars Helicopters, Multirotors, Boats, hover craft, etc.They are mostly used to control the control surfaces (RC Planes) or for thrust vectoring mechanisms (hovercraft, boats, multirotors) or for steering mechanisms (RC Cars).Hobby grade servos are further classified as micro, standard, giant based on the torque they can provide, however their working principal is just the same.Based on speed of operation they are classified as Analog or Digital servos, Digital servos provide greater speed but consume more power.Speed of a servo motor is defined as time taken for shaft to move from 00 to 600 after the application of signal. In this article we will be using an ARDUINO clone board viz. FREEDUINO.

H-bridge using transistor
This project and circuit finds a huge application in the area of robotics to control motor direction. This circuit uses the basic concept of transistors as a switch. H-bridge using transistorTransistor with proper biasing can be used as switch, i.e. it can be used to toggle between the two states of a switch on or off. This configuration of transistor has been used in H-bridge to drive a motor in both clockwise and anticlockwise direction. This circuit derives its name from the English alphabet “H”, which closely resembles the circuit pictorially. The circuit based project can be divided into two parts. The first part explains the concepts behind the working transistor as switch and the second part the function and operation of H Bridge. Keep on reading to find out how the circuit is constructed and what makes it work.
DC Gear motor rotation control
Here is very useful application that controls the number of rotation of 12 V DC gear motor with very low RPM (1,2,3,5 or 10 etc).You may find lots of [[wysiwyg_imageupload::]]applications of this project in robotics, CNC machines, manufacturing industries etc. Here are some of the examples In any PCB cutting or PVC pipe cutting CNC machine (or any other automatic cutting machine) first the linear dimensions are calibrated in terms of number of rotations (e.g. 5 rotations = 1 CM), then by adjusting the number of rotations as per required dimension one can easily move the cutting tool to that distance (e.g. for 1 meter 500 rotations). In robotic arm application, if the arm has to move to a specific position then first its movement can be calibrated in terms of number of rotations of motor. Afterwards once we program and set the number of rotations for a button, the arm will always move to that position when that button is pressed.
DC Motor Control with VC++
This project is Microsoft Windows based program written in Visual C++ to control DC motor. Visual C++ is one of the very efficient, effective more user [[wysiwyg_imageupload::]]friendly software. Let us see the main function as well as the additional features of this application. Mouse as well as keyboard interface provided. All the controlling actions at your fingertips Four degree of motion control is achieved for single motor. (1) Motor rotates continuously at constant speed (2) pulse wise rotation means motor rotates for less than one revolution (3) motor rotates with desired speed for fix duration of time (4) motor rotates till mouse button is pressed and moved. One can vary both the parameters of motor speed and direction. DC motor will rotate like stepper motor in pulse wise rotation mode. Keep on reading to find out how simple controls over DC motor can be managed using Visual C++.
How to use a PMDC Motor in Electronic Circuits
Electric motors are the most convenient devices in use which can convert the electrical energy into mechanical energy. Electrical motors converts the electrical [[wysiwyg_imageupload::]]energy to rotational motion which can then be easily converted to any kind of mechanical motion like moving a robotic arm, moving a needle in a sewing machine etc. The Permanent Magnet Direct Current (PMDC) motors are especially useful since they are very easy to control, produce a lot of power and come in various sizes, shapes and voltage ratings. When used with electrical or electronic circuits one must be careful about certain things like the current consuming, torque, RPM etc. This article mainly discusses those things and also the details of circuits which can be used to drive the PMDC motors. Continue reading to find out how PMDC motor can be easily used in electronic circuits.
Single switch motor on/off.. Clockwise/anticlockwise
Shown here is an easy to construct electronic circuit through which a motor can be made to run in both directions i.e. clockwise and anticlockwise. An interesting [[wysiwyg_imageupload::]]fact that adds to the curiosity of the circuit is that this is done by pressing a single switch. This project finds a good application in areas of robotics. The commonly used H-Bridge circuit uses two control signals to control both the directions of the motor. Before we begin explaining the circuitry, let’s have some information about the H-Bridge circuit.H Bridge CircuitMainly used to control DC motors and stepper motors, H-bridge divides the voltage on the either side of the load. In this circuit, two IC555 timers form the H-bridge circuit around the motor. These 555 timers work in astable mode. Let’s find out more about how the circuit works.
Motion Controller using Stepper Motor
This system is the example of close loop control system for maintains the speed of stepper motor constant. The speed of stepper motor is sensed and feedback to controller. Controller will compare it with set value and if there is deviation then it will either increase or decrease the speed.In most of the industries the constant speed of motor is required and that should not be fall / exceed beyond specified limit. to get the precise RPM and control stepper motor is the best.The stepper motor is placed on top of laser as shown. The slotted wheel is coupled with the shaft of motor. The wheel is such a big that it can interrupt the laser beam falling on LDR. Now as the motor rotates the slotted wheel also rotates. The beam will fall on LDR only when the slot comes. This will produce one pulse. So every time when slot come in line with LDR and laser, one pulse is produced. Thus the rotation of motor is converted in to pulse that can be counted.

Temperature Dependent Fan
Obviously you might have seen so many temperature controller and indicator applications using different micro-controllers, micro-processors or other controlling devices. But this is the actual application of temperature controller that controls speed of DC fan as temperature varies. It is not a simple ON-OFF type controller that switches fan ON / OFF when temperature increases / decreases certain limit. But its continuous type controller that continuously varies speed of DC fan as temperature increases / decreases. That is a demo of actual industrial application.
