 DIY Electronic Beginners Fun CD4017DIY Electronic Beginners Fun CD4017 colourful sound-activated rotating LED lights kit can intuitively display the functions of CD4017. It is a kit for learning counters, frequency dividers, and lantern controllers. At the same time, the kit has excellent effects, is exciting and practical, and is also a material for beginners to get started.
Circuit principle: Q1 and its peripheral circuits form a simple amplifying circuit. MK converts the sound signal into an electrical signal coupled to Q1 via C2 for amplification. A voltage signal with significant and low changes is formed at the collector of Q1. The voltage with sufficient amplitude is sent to CD4017 for counting. The input terminal (14 feet), every time a pulse arrives, the high level of the counter’s Q0-9 output moves 1 bit, in turn, to light up the corresponding light-emitting diode, thereby producing the effect of a water lamp.
Features :
  • Circuit board: 1.6mm thick, 48mm diameter
  • Supply voltage: 5V DC voltage
