Those that can be reached are shown on the drawing.īy adjusting the frequency of the oscillator you can set the length of time it takes for any given output to go high. Although it's a 14 bit counter, not all of the bits are accessible. The green Led flashes while the oscillator is running: and the IC counts the number of oscillations. The oscillator consists of the two inverters connected to Pins 9, 10 & 11 and its frequency is set by R3, R4 & C3. The Cmos 4060 is a 14 bit binary counter with a built in oscillator. Pick the one that best suits your application. The first uses less power while the timer is running and the second uses less power after the timer stops. The main difference is that when the time runs out, Version 1 energizes the relay and Version 2 de-energizes it. O’Reilly members experience live online training, plus books, videos, and digital content from nearly 200 publishers.These two circuits are multi-range timers offering periods of up to 24 hours and beyond.

This chapter first delves into the operation of this IC and its 74HC. That project used just three of its outputs to change the color of an RGB LED. If you previously built the color-changing light box in Chapter 6, you have already met the 4060 14-stage binary ripple counter IC. You could use the board for educational purposes to show how to count in binary, or you could build multiple boards to produce a mock-up of a mainframe computer that looks as though it is performing some really complex calculations! T HE PROJECT IN THIS CHAPTER DEMONSTRATES THE operation of a binary ripple counter IC by building an experimental board that shows how each output of the IC operates, using a single LED indicator per output.
