This is a Rain LED circuit using a NE555 and a CD4017. 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.
After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!
