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.

Electronics Circuits

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.
