LED on when LED was off (Exited after 1 hour) LED off for 5 seconds when LED was on. (PIR detection disabled during this period) LED will switch softly on and off. If pressed during this fading, ...

PIR Motion activated RGB led stair lights for Arduino. Goal of this project is to have animated RGB WS2812B stair lights. The lights are activated by 2 PIR Motion sensors located at the top and bottom ...

It should be a piece of cake if you program your Attiny85 chip (not Digispark) using your existing Arduino IDE with the help of one “USB tiny ISP (v2.0)” programmer. The software/Arduino sketch /* * ...

Because there are three lights, each LED panel is connected to a transistor. Included is a fourth transistor for a future upgrade to have lights that fade in and out with time. Use a 220 ohm resistor ...

PIR Sensor Module Parts. The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens.. The contours on this plastic helps in ...

1. At the start, Pins of the Arduino are initialized which will be later connected to the LED and the buzzer. A variable is also declared that will store some values during run time. Then the initial ...

In this security light circuit, High level (3.3V) output from SB0061 is used to switch on six 5mm white straw hat LEDs through a solid-state switch realized using transistors T1 & T2. PIR sensor ...

Abstract: In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the ...

This paper describes about efficient automatic street lighting system using Graphene coated (Light Emitting Diode) LED. Nowadays, LED street lighting is becoming more and more popular among developing ...
