DC motor driver circuit in the following circuit images can be used for DC motor drivers and can control the direction of rotation in two directions with a DC motor rotation speed can be set. Under the DC motor driver circuit is quite simple and is built with a voltage comparator circuit 741 IC Op-Amp and a pair of NPN and PNP transistor driver. D

C motor driver circuit in the following figures can be worked on a symmetrical voltage source ± 9 volt and 6-9 volt DC motor load. DC motor circuits in detail can be seen in the following circuit images. Simple DC motor driver circuit above can control the direction of rotary speed control of DC motors and DC motor rotation. Above DC motor driver consisting of the comparator and power a DC motor driver. Parts of comparator function is to provide control signals to the power transistor driver. At the time of the control voltage (pin 3) is higher than the voltage at pin 2 then the voltage comparator IC 741 IC 741 will provide the output voltage with a positive level, it will provide forward bias to reverse bias the transistor Q1 and the transistor Q2. then the voltage at pin 3 is lower than the voltage comparator IC pin 2 then gave the 741 will output a negative level, so that the transistor Q2 gets forward biased and reverse biased transistor Q1 gets. The transistor is used as a DC motor driver is a type TIP31 transistors for Q1 and Q2 TIP32 for. At the forward bias of Q1 and Q2 have the reverse bias the DC motors have a positive current source through Q1 so that the DC motor to move in a clockwise direction. Then at Q2 and Q1 gets the forward bias to reverse bias DC motors have a negative voltage source to a DC motor to move counter-clockwise. The size of the bias voltage on the base of Q1 and Q2 bidirectional DC motor...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
