The CD4026 is an integrated circuit (IC) that works as a counter from 0-9 with an integrated decoder for a 7-segment display. I think it is an ideal beginner circuit for anybody who wants to learn electronics. In this tutorial we will go through the very basics of this IC and learn, step by step, how to connect it to pushbuttons, a 7-segment display, and a battery, to build our own counter!
