Music tone base dancing LEDs glow according to the sound of the music. The researchers found that the rhythmic lights are speeding up the brain waves that improves higher concentration levels. These simple electronics circuits projects are used to changing the  LEDs according to the sound of the music. This project uses a microphone that picks up the musical sound and is amplified through the amplifier. Then, this amplified signal triggers a sequence of LEDs using an intermediate circuit. Hence, LED flashing is achieved by changing the beat of input musical signal.

This project is designed to detect vehicle movement on highways to turn ON only a block of LED lights ahead of it (vehicle), and to switch OFF trailing lights to save energy. This project saves the energy, which is achieved by sensing an upcoming vehicle, and then to switch ON a block of street lights ahead of the vehicle. If there are no vehicles on the highway, then all the lights remain OFF without human intervention. Thus, we can save the energy using a flashing led circuit arrangement.

The intensity of street lights is required to be kept high during the crowning hours. As the traffic on the roads tends to decrease slowly in late nights, the intensity can be reduced progressively till morning to protect energy. Therefore, the street lights switch ON at the dusk and then switch OFF at the dawn automatically. The process repeats every day. The project is designed for LED-based street lights with auto intensity control using solar power from photovoltaic cells. As awareness for solar energy is increasing, more and more individuals and institutions are opting for solar energy. Photovoltaic cells are used for charging batteries by converting the sunlight into electricity. This is a microcontroller LED project that works based on PWM pulses provided by the microcontroller to control the intensity of the light.

High-Intensity Discharge lamps (HID) generally used in urban street lights, which work based on the principle of gas discharge, and thus, the intensity is not controllable by any voltage reduction method as the discharge path gets broken. LED lights are the future of lighting, because of their little energy consumption and long life they are fast replacing conventional lights world over. White light-emitting diode (LED) replaces the HID lamps where intensity control is possible by pulse width modulation.

This project is designed to automatically control the intensity of light by an Arduino board using solar power from photovoltaic cells. Present days, the usage of solar energy is increasing from institutions to industries. Solar panels are used for charging batteries by converting the sunlight into electrical energy. A charge controller circuit is used to control the charging of the battery. The intensity of street lights is required to be kept high during the peak hours. As the traffic on the roads to decrease slowly in late nights, the intensity can be reduced gradually till morning to save energy. Hence, the street lights switch ON at the dusk and then switch OFF at the dawn automatically.
