This is a fun-loving project based on the Arduino platform. The project creates color light effects with sound level sense by an onboard condenser microphone. The project consists 20 x WS2812B RGB LEDs, an Atmega328 micro-controller, condenser microphone along with pre-amplifier, RCA...

This creative idea is suitable for a stairway with 16 stairs, each stair can have a 12V LED. It has two sensors one at the start and one at the end of the stairs and when the sensor trigered at any end it starts a process of lighting each of the steps in a progressive cycle starts....

This motion sensor LED ceiling light board has been designed using 4 white LEDs each of 1-3W, PIR sensor module, Atmega328 microcontroller, low ohm IRLR7843 MOSFET, and few other components. The PIR sensor detects the infra-red rays emitted by human motion within the detection area...

This is a Knight Rider LED Light and it is one of the best Arduino projects for beginners. This board drives 16 high-power LEDs to turn them ON one by one sequentially. This is an open-source Arduino compatible project that contains 16 high current MOSFETs, Atmega328 microcontroller,...

The circuit presented here is a LED light stick which changes its color in respect with the room temperature. This is an Arduino compatible open source project consisting of 20 x WS2812B Addressable RGB LEDs, LM35 Temperature Sensor and ATmega328 microcontroller. Atmega328...

In general, generating an LED fade effect requires a microcontroller or another expensive circuit. We have built this low-cost LED fading board using an inexpensive 555 Timer. The 555 timer is used as an astable multivibrator, which generates low-frequency pulses, further, this pulse...

The project shown here is a cheap 60W LED dimmer for 12V LEDs/12V LED strips. The circuit is based on the very popular, versatile, and low-cost 555 timer IC, NE555 IC generates a PWM signal and IRF540 MOSFET works as output driver for the LEDs. In this circuit the 555 IC used in an...

This project is built for fun loving users to create a 24 LED bar-graph for light effects that can be driven using Arduino or another microcontroller. The project consists of 74HC595 x 3 chips, and 24 LEDs of Red, Green, Blue, and Yellow colors. The project helps the user to...
