H bridge Control the Direction of Rotation for DC motor Circuit Diagram

This circuit can control the direction of a DC motor., It has many applications that are necessary to operate a motor in both directions, clockwise and counter-clockwise (forward and backward). One way to accomplish this is to start the engine in a circuit arrangement of transistors called H-bridge. H bridge is an electronic circuit which enables a voltage is applied across a load in either direction. This circuit is often used in robotics and other applications to allow DC motors to become bi-directional.

H-bridge Control the Direction of Rotation for DC motor Circuit Diagram

List of components

PARTS LIST
R1, R2, R3, R4 220Ω
R5, R6, R7, 1K Ohm
D1, D2, D3, D4 1N4001
D5, D6 LED
Q1, Q2 2SD313
Q3, Q4 2SB507
PB1, PB2 switch
M1 12V DC MOTOR

In this circuit usually PB1 and PB2 are open. Thus, the bases of the transistors are grounded. Hence Q3 and Q4 are turned on, Q1 and Q2 are turned off. The voltages at both terminals of the motor is the same and thus the engine is switched off. Similarly, when both PB1 and PB2 are "on" motor is turned off. The LEDs indicate the direction of motor rotation.

NE566 Function Generator Circuit Diagram

The NE566 Function Generator is a Voltage-Controlled Oscillator of exceptional linearity with buf fered square wave and triangle wave outputs. The frequency of oscillation is determined by an external resistor and capacitor and the voltage applied to the control terminal. The Oscillator CAN be programmed over a ten-to-one frequency range by proper selection of an external resistance and modulated over a ten-to-one range by the control voltage, with exceptional linearity.

TDA2030 complete tone control

At this time I present a series of amplifiers that use IC TDA2030, but this series is equipped with a tone control. Tone controls include Bass, Treebel, and Volume. Power amplifier and tone control has been put together in a single PCB. As well as its power supply circuit was also used as one with the power amp, and tone control. Making it easier in the installation and will look neat. Schematics Layout PCB PCB design This amplifier is a mono amplifier type, can be modif for guitar amplifiers. If not coupled amplifier (mic preamp) then you must deactivated potensio treble and bass, why? because if not using a mic preamp and still maintain potensio treble and bass sound input (input) from the guitar will not or the maximum discharge is not tight on the speakers. So you must deactivated a way to decide which directly connected capacitor with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.

Simple Preamplifier and High to Low impedance Converter Circuit Diagram

This is the Simple Preamplifier and High to Low impedance Converter Circuit Diagram. This circuit matches the very high impedance of ceramic cartridges, unity gain, and low impedance output. Simple Preamplifier and High to Low impedance Converter Circuit Diagram By `loading` the cartridge with a 2M2 input resistance, the cartridge characteristics are such as to quite closely compensate for the RIAA recording curve. The output from this preamp may be fed to a level pot for mixing. Sourced By: Circuitsproject
