CD4017 Voice control rotating colorful LED circulating water lamp Kit DIY microphone sound electronic control
Product overview
This kit circuit uses sound control 10 LED water luminous, LED arranged into a circle, to sound pulse signal, LED like water light cycle, can be very intuitive display CD4017 function, is learning counter, frequency divider, color lamp controller suite. At the same time, the kit has a good effect, very interesting and practical.
Product parameters
Supply voltage: DC 5V
Board size: 48mm in diameter
Using tips
1. Resistance The resistance value must correspond to that marked on the board
2 LED long feet are positive, the board is close to the white hole is positive.
3. The electrolytic capacitor has a positive foot, and the hole on the side of the board with a slash is a negative pole.
4. The reverse notch of the chip base and chip should be consistent with the reverse notch marked on the board.
5. Pay attention to the positive and negative power supply, positive , negative -, will burn out the chip.
6.LED color position can be placed at will.
 
The working principle of
Q1 and peripheral circuit of simple circuit, MIC will sound signal is converted to electrical signals, enlarge the C3 coupled to the Q1, form of high and low voltage signals in Q1 collector, enough to CD4017 counter input voltage amplitude (14 feet) every arrival a pulse, counter Q0-9 output high level of sequence mobile one, Light the corresponding LEDS to create the sensation of flowing water.
