In this Arduino project having main components are Arduino kit, DC motor L298N Motor Drive IC. Here we have different ways how to control a DC Motor and also this is quite popular for many reasons which are Arduino DC Motor control using L298N. A DC motor is the simplest motor that beginners and hobbyists know. It is very easy to use: connect the two motor cables to the two terminals of a battery and that's it! Your motor starts spinning. If you want to control the rotational speed of a simple DC motor , there is a technique called PWM DC motor control. The pulse width modulation or PWM signal generated by this technique allows us to control the average voltage delivered to the DC motor . Now, the average voltage applied to the DC motor depends on what is known as the work cycle of the PWM signal. The working cycle of a PWM signal is nothing more than the ratio of the time the signal is activated or is HIGH to the total duration of the signal, that is, the time signal. The ...

Water Level Controller The water level controller, which uses the 8051 microcontroller project , helps automatically control the water motor by detecting the water level in a tank. In this article, you will learn how to detect and control the water level in a tank or other container. This system monitors the tank water level and automatically turns ON the Motor when the tank is empty. The Motor is turned OFF when the top tank or tanky is full. Here the water level of the tank is shown on the LCD screen (liquid crystal display). With this system, we can also avoid overflowing the water. Here we are designing the circuit which is used to detect and control the water level automatically in the overhead tank using 8051 Microcontroller . Components Required for Water Level Controller using 8051 Microcontroller  AT89C51 Microcontroller (or any 8051 based Microcontroller) 8051 Programmer (Programming Board) 11.0592 MHz Quartz Crystal 2 x 33pF Capacitor 2 x 10KΩ Resistor (1/4 Watt) 10µF Ca...

TPA3122D2 Class D Audio Amplifier TPA3122D2 Class D Audio Amplifier Circuit In this amplifier circuits mainly TPA3122D2 IC is used as a class D audio amplifier and it can gives output up to 15W of power at 10% distortions. The main advantage of using a class D amp , especially TPA3122 is the fact that this IC doesn’t need a heatsink because it has a high efficiency.
