How to Make a Simple Inverter

The inverter is an electronic circuit that converts DC voltage into AC voltage. The circuit is very useful when the power goes out or the time when we do not have an AC voltage source. Inverter only requires an accumulator to operate. So the advantages of this circuit (inverter) compared with an AC voltage generator that uses fuel to work is the inverter does not cause noise when being operated, does not cause air pollution and easier to carry anywhere. So, how to make a simple inverter? We must learn the parts of an inverter. The parts of an inverter include: driver stage and power stage. You can see in the image below. 2.   Construct each of the parts of an inverter.     Driver stage Driver stage consists of...

DC Motor Driver Using L298

This post has more to do about the microcontroller and its programs. Here I will discuss how to drive the movement of a dc motor with the input of the microcontroller AT89S52 or ATMega? If we directly connect the microcontroller to the DC motor, the DC motor will not be able to move, it caused the output of the microcontroller has a low current rate of about mA. So, we need another component that can strengthen the output of the microcontroller. L298 is a simple DC motor driver is most appropriate to be used as a solution to this problem, because this IC can pass currents up to 4A and the voltage to 46 volts. L298 is a dual full-bridge driver, said it's because it has two enable inputs, two pairs of input and two output pairs. We can see...

Adjusted The Servo with IC 555

Servo is a device that is widely used to create a project, which is associated with movement, such as tool motion on the robot, each using a servo joints. Servo motor movement is more subtle than the dc or stepper motor movements. Most servo has a work rate of 50Hz (20ms) at the point where a pulse between 1 and 2ms is used for command output to drive the servo. We can build a simple circuit to adjust the servo movement can be built using IC 555. We must be very familiar about this IC, because IC is widely used in applications as an oscillation, wave generator, timer, etc.. By adjusting the potentiometer on the circuit above, a 555 timer IC can generate pulses every 20ms with a duty cycle of between 5% and 10% (1-2ms). This circuit operates...

Generator Pulse with IC 555

Many devices or electronic components that can be operated with an electric pulse, even they can be adjusted by electric pulses. For example, a stepper motor, for controlling the stepper motor, required stepper motor controllers which produces periodic pulses. Motor rotational speed is determined by the frequency applied to the stepper motor. Electric pulses can be generated by the oscillator circuit that uses a IC 555 with astable mode. This circuit operates at voltage range 10-12 V. Frequency generated by this circuit can be calculated by the formula: F= 1/1,44 {(P1+R4)+ (2(P2+R3)} C2 Duty cycle of this circuit can be adjusted by changing the value in P1 and P2, and the frequency also can also be changed by varying the value in C2. D1,D2...

MAKES A POWER SUPPLY 12V 5A

Today, when we want to make a device that uses a 12 volt voltage source, we can not possibly carry a large 12 volt PSA's everywhere. Now, to complement the tools that we make it, we must also make an appropriate voltage source with the tools we create. Here, I will provide a circuit that can be used for devices that operate at a voltage 12 volts. Many Power Supply circuits is also available on the Internet for free but may be making the circuit that requires a high cost, such as power supply circuit using the LM388, LM388 price per one unit rather expensive. I give this circuit requires only a low cost. This is the its PCB layout. Transistors can be replaced with another type with the desired current rating. For the type 2N3055 transistor...
