Product introduction:The adjustable speed water lamp experiment kit is a product developed for the spot check of electronic assembly and debugging skills. The circuit design uses the CD4060 chip widely used in digital circuits to form an oscillator, and controls the LED flashing through the CD4017 counting output.
It is a good product worth learning and circuit analysis.The CD4060 in the circuit is composed of an oscillator and 14-level binary serial counter bits. The junction of the oscillator can be RC or crystal oscillator circuit. This circuit adopts RC structure. The frequency of the oscillator is determined by C1 and RP, and its period is T=2.2 × RP (t part of access circuit) × C1 . The oscillation pulse is output from the 5th pin after frequency division as the counting pulse of CD4017. The 4 pin CP end of CD4017 is connected to the high level, the 3 pin EN enable end becomes the trigger end, and Y0~Y9 is connected to 10 LED D1~D10, which are arranged in a circle in turn. When the circuit is powered on, Y0~Y9 outputs the high level in turn, so that the LED lights up in turn, forming a flowing aperture. Adjusting the size of RP can change the oscillation frequency and the flow speed of LED.
