It is mainly useful to music lovers. After some time, the door would be closed automatically. It can be used in industries and surveillance systems.
Blanking input is used to show off or vary the brightness of the display. This Bluetooth receives the commands from the Android application device using wireless communication. This circuit works on analog to digital conversion principle.
It is fully functional based on the password. It helps in mobile phones tracking which are used for spying. It produces different tones or sounds depending on the frequency range. This article describes the circuit that switches the street lights on detecting vehicle movement and remains off after fixed time. Two identical circuits are needed, one is for left and the other is for the right.
This project describes circuit that rotates solar panel. This circuit works as a continuity tester device which tests the continuity of the wire at hand. All you need is to just place this circuit in front of the locker or below the mat so when an unknown person come and walk over the switch, the circuit will trigger, and the sound of alarm comes.
So by using this circuit, we can increase the lifetime of the battery. We built the circuit using a microcontroller which scans the input from push buttons and displays the corresponding number on a display device. It provides the considerable amount of brightness required to do our daily tasks. It is very flexible and is employed in many circuits like a voltage regulator.
This voltage is amplified and applied to the circuit in order to make the led turn off. It provides a considerable amount of brightness required to do our daily tasks. Using this remote, we can control the appliances within the range of meters. This saves the power consumption and is low cost. This Stun gun circuit is mostly used as a weapon to stun or send shock waves to the target with the intention to weaken or paralyze it.
We made this project using Arduino. Please help me out and reply soon. This is one more interesting and useful project.
So, with the help of this unique circuit, pdf xchange viewer version 2.0 we do not need to move from one place to open and close the curtain. This Voltage regulator circuit is used to get fixed voltage at the output without depending on the input voltage. This allows you to watch your own program without anyone changing the channel or volume.
This circuit is a temperature sensing as well as alarm circuit. The main heart of this circuit is timer. This is achieved here by using a step down transformer V of mA rating. We can also control a robot using this technology by making some modifications.
This is the similar project we have done already but here we are using different module timer circuit. This is a pocket-sized radio circuit. The main principle of this circuit is to produce sound depending on the light intensity falling on the circuit. Mostly useful at movie place, shopping malls etc. It is an indispensable tool to check broken wires and undesired shorting of wires.
It is helpful to count the number of persons entering or leaving a room and to display it on a screen. This circuit can also work as an emergency light.
It is more useful when the owner is not present in the home for a few days. This is without using the microcontroller. Very interesting project for who are interested in robotics too. It can also be used as a temperature detector.
Here is the circuit diagram and working of w subwoofer amplifier circuit. The puff applied to the mic is converted into a voltage whose value is very small. This prevents the deep charge of the battery. Very simple and low-cost hardware project. Read this post for complete details.
If you are a new driver then it is very difficult to judge the distance while parking the car. This circuit produces a sound similar to the police siren. Morse code is very old and versatile technique to send text messages using wireless media.
It really helps us to work hard. It is used in security applications.
Here are the circuit diagram and working of w subwoofer amplifier circuit. This is a circuit diagram of digital dice which is nearly unbiased.
Can be implemented as free electronics projects. The multivibrator is an electronic circuit which will work as two-stage amplifier operating in both stable and a stable mode. Electronics projects with circuit diagram free as given below. Projects are really great.
The main principle of this circuit is to rotate the stepper motor stepwise at a particular step angle. This circuit helps you to guard your precious documents as well as jeweler from intruders or theft.
Electronics Projects With Circuit Diagram
This is a simple alarm circuit which helps in ringing a warning alarm when someone tries to steal the luggage. This air flow detector circuit can be used to detect the flow of air in areas like the car engine. This circuit can be used in the museums to protect the valuable things.
This circuit helps the soldering iron to turn off automatically when it detects overheating and thereby avoids it from getting damaged. The main principle of the circuit is to detect the human using the human detection sensor. This is a simple circuit which is more useful to save our resources, energy, and money by installing in your homes.
