Reading time: 2 minute For those who want to build a sequential dynamic light for 8 LEDs, this electronic DIY IPRS kit is recommended because its construction is extremely simple. The assembly is based on 3 integrated circuits: CDB 404 (SN74F04N) - the clock generator and two CDB 495 travel registers (SN 7495 / 74LS95B).
Reading time: 2 minute The presented project turns on 5 LED blocks in turn. Each control block contains a maximum of 20 LEDs. The LM555 integrated circuit acts as an oscillator and the CD4017 as a decoder.
Reading time: 2 minute Also called "Knight Rider", the presented circuit lights 4 LEDs in turn. The operation of the project is based on two ICs: LM555 and CD4017. The LM555 integrated circuit acts as an oscillator and the CD4017 as a decoder.
Reading time: <1 minut The presented project lights 3 LEDs consecutively. The circuit is relatively simple, being designed of 3 NPN transistors, 3 polarizing capacitors, 3 LEDs, a potentiometer and some resistors.
