I have divided this circuit into two parts, the first with NE555 generates an (adjustable) frequency which issent to the CD4017 (Pin 3 NE555 to Pin 14 CD4017) The second part of the circuit, with CD4017, manages the LEDs, making them run at a speed set by the frequency that I just told you about (from NE555). LED speed can be adjusted by a 47KΩ trimmer... and in this second version I added some electrolytic capacitors to create a small bright trail effect. Components: 1x NE555 IC 1x CD4017 IC 1x 330Ω Resistor 1/4 Watt 2x 1KΩ Resistor 1/4 Watt 1x 47KΩ Trimmer 1x 1uF @25/50/100V Electrolytic Capacitor 10x 4.7uF @25/50/100V Electrolytic Capacitor 1x 8 pin DIP (not mandatory if you solder the IC on PCB) 1x 16 pin DIP (not mandatory if you solder the IC on PCB) 20x LED 5mm (any color) 1x LED 3mm (PWR LED) 1x 1N4007 Diode (protection against polarity reversal) PCB: (Ready for jlcpcb.com): https://drive.google.com/file/d/1bhec... *Don't use my PCB for profit or sponsored videos.
