LED Knight Rider Using 4017 and 555 IC's In this 4017 Knight Rider circuit, the 555 is wired as an oscillator. It can be adjusted to give the desired speed for the display. The output of the 555 is directly connected to the input of a Johnson Counter (CD 4017). PARTS LIST R1 22kΩ R2 220Ω VR1 50kΩ...

Arduino Project Knight Rider In this tutorial, eight LED's are interfaced to the Arduino Uno board. A program is then loaded to the Arduino that will turn the eight LEDs into a "Knight rider" display. Components Besides a breadboard, Arduino Uno and USB cable, you will need: 8...

Easy Build a Circuit on Breadboard Use LED This tutorial shows you how to build a very simple circuit which lights up a single Light Emitting Diode (LED). Componenct: 1 pcs 1k resistor (1000 ohm, brown - black - red) 1 pcs 5mm red LED You will also need: A breadboard Breadboard...

Easy Build RF Receiver / Transmitter Pair (27 MHz) In this article we will build a simple rf receiver module that works at 27 mhz and turns on an LED anytime the signal from the transmitter is detected. A very simple idea, but as you will soon find out, a lot goes into making...

555 IC To Build LED Flasher Components In addition to a breadboard, wire links, 9V battery and battery clip, you will need: 10k resistor (brown - black - orange) 4k7 resistor (yellow - violet - red) 1k resistor (brown - black - red) 100uF Capacitors 10n (0.01uF) Capacitors NE555...

Make a Timer With IC 555 Make the timer electronically can use the NE555 IC is designed specifically as a timer or multivibrator. Timer NE555 IC made it very simple and operated using a flexible DC voltage source of 4.5 VDC to 15VDC making it easier for us in the paint the...
