LED chasser by using 4017 ic.                         LED chasser is row of leds    connected in a line.  In this project we drive the 10 leds by 4017 ic. Which is decode ic it is used as a leds driver.  Pinout of ic.  Connect as shown i  figure given below.  Connection diagram.  We connect all output of ic to positive led of led and negative of each led is connected to ground.  Connect reset to ground with 1k resistor. And enable is also connected to ground,  After that we apply the clock input to ic (maniuly or by using 555timer).  List of components required (Amazon links) 1.  4017 ic   https://amzn.to/2Jei9Yc        2.  8 pin ic base     https://amzn.to/2Pdjjaw 3.  LED light     https://amzn.to/33UbOJn    4.  bread board       https://amzn.to/2N3XIyx 5.  jumper wire.       https://amzn.to/2N8mVHY 6.  Resistors.         https://amzn.to/2N8mVHY By varing the input signal, we can vary the    spee

Plus generator using 555 timer ic.          https://youtu.be/AjMR6dglbgw .  This 555 timer ic generate a plus according to your connection. This device only generate square pluse only with variable duaty cycle and frequency.
