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...
