How to Cascade IC 4033 in Multiple Digit Counter Display
In this article I will comprehensively explain how to cascade many 4033 ICs together for driving multiple 7 segment counter displays. In one of my previous articles I have uniquely explained the role of pin#3 and pin#4 which become crucial when the IC 4033 are intended to function for driving multiple displays. Multiple Digit Display […]
Make this Temperature Indicator Circuit with Sequential LED Display
In some of my earlier articles we have seen a few simple and interesting temperature indicator circuits, in this article we will try to upgrade one of them into a sequential form. All these circuits are useful in some or the other ways, however these are not equipped with step wise temperature level indicator arrangement […]
