  • Simple Two digits counter using CD4026 April 19, 2014
    This is a simple two digit counter using CD4026 as main parts can display with LED 7 segment 0-99 number There is a reset button to restart. 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 […] […]
