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.

单开机电动机打开/关闭。顺时针/逆时针
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.

温度依赖风扇
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.
Three Stage Sequential Timer for DC motor control
In most of the industrial processes it is required to rotate DC (or AC) motor forward and reverse for desired time. First motor rotates forward (clockwise) for some time (say 2 – 3 min) then it stops for some time. Again it rotates reverse (anticlockwise) for some time and rests. This process repeats every time when gets triggeredSequential timer is widely used circuit in industries because in most of the industries all the processes are of chain reaction type. That means one process ends and it triggers next. The last process triggers first process when it ends. And thus the cycle continues. These sequence timers are micro controller based multi-functional and programmable.But here we have a sequential timer using simple IC555. So let us see how it is done
Wireless DC Motor Speed Control using IR and IC555
这是一个非常有趣的应用程序。我们将vary the speed of DC motor from a remote place without any wire connection. I am using PWM (pulse width modulation) method to very the speed of DC Motor. To make it wireless I am using IR transmitter and IR sensor. There are two sections in the circuit 1) PWM generator with IR modulator and 2) IR receiver and motor driver. Transmitter generates PWM wave of 50 Hz (20 ms) and modulates it over 38 KHz frequency. The IR sensor on receiver side will demodulate the PWM wave and drives the DC motor.
使用激光和IC555的无线步进运动速度控制
An interesting project explaining how can one control speed of a stepper motor from a remote place without using any wires. A LASER and LDR are used for this purpose. From the transmitter, low frequency pulses are sent to the receiver using LASER diode. On the receiver side, a LDR will receive these pulses which will further trigger mono stable multi-vibrator to regenerate same pulses. These pulses will drive the stepper motor through driver circuit. So as anyone changes pulse frequency from transmitter, the stepper motor speed will change accordingly. The project uses a pulse generator, LASER, LDR, monostable multi-vibrator, current drive, stepper motor, counter and OR gates.
