LED Fader - With or Without Arduino

“Have an awesome project in mind using some LEDs. In that project I will be using some LED Fading Effect and few LED Chaser Circuits. But before jumping onto that, I thought I should create a short tutorial and show …

Heart Shape LED Lamp

“This is my first instructables project. you can join with mw to do more amazing project like this. In this project, we make a simple LED heart shaped flasher circuit using NE555 timer IC. This is simple LED flasher circuit …

Water Level Indicator With Temporary Alarm & Water Flow Sensor

“There are many countries and people who depend on the water tank to get the water for their home as I am. In the lockdown, my dad keeps climbing the stairs to know the water level and to secure our …

LED Juggling Knives

“This project was inspired by one of my friends, who is an avid juggler. He was looking for glow in the dark juggling balls and I wanted to try my hand in building it. As I worked through the design …

Match the Color Game Using 555, 4017 and RGB LED

“I created a circuit in which random colors are picked and where the user must attempt to match the colors as many times as possible for a high score as they blink on and off from left to right at …

LED Chaser Circuits Using IC4017 and Arduino

“A Chaser Circuit consists of a clocked IC or other electronic unit like an Arduino that drives an array of LEDs in such a way that individual LEDs (or small groups of LEDs) turn on and off in a predetermined …

Save Water With Over Flow Alarm

“Water plays an important role in our day-to-day life. Although our mother earth is covered with 71% of the water we have just very little; that is approximately only 1.2% which is available for domestic usage. As we being …

LED Fading Effect / LED Strobe using 555

“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 …

Trollduino V1.0

“Response to Hackaday comments section: a 555 timer in Arduino form factor “That’s stupid! Why use an Arduino when you could do the same thing with a 555?” - representitive comment on any Hackaday post that describes any Arduino project …

60W LED Dimmer for 12V LEDs using 555 Timer

“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 …
