It can be applied to, for example, counting products, counting people into the library, and more. The working principle As circuit in Figure 1. The IC1, IC2-CD4026 4026 […] […]
  • Morning alarm with sunlight using IC-4011 April 17, 2014
    This is simple circuit that we makes in hobby time or toys for my son but really uses. It will have sound alarm when morning like a normal clock alarm with lighting sensor same clock. We use a IC-4011 CMOS only one and a few components also can generate pulsating tone like a general clock. […] […]
  • Simple Electronic clock sound using IC4011 April 17, 2014
    The sound of insects such as crickets, cicadas, resulting from flutter briefly. We can use a multivibrator to connects as sound generator circuit to imitate these insects sound. Some electronic clock alarm tone also sounds similar to these insects. As Figure 1 is simple clock alarm sound generator that can assemble on a breadboard right […] […]
  • Simple Tone Generator using inverter logic form. April 16, 2014
    We use a simple oscillator circuit in very many projects. I like to use a inverter logic gate since it is easy and cheap. But we do not use it directly. Mostly I use IC4011 nand gates since includes for separate four positive logic nand gate on a single silicon chip. Enough for general use […] […]
