💎【Music Dream Light】:This kit can be used as electronic skills in vocational colleges, electronic training, and electronic enthusiasts to learn. It uses a 14-level binary counter CD4060 with an internal oscillator circuit as a control chip to control 12 red, yellow and green LEDs to flash. Adjusting R3 can change the speed of LED flashing. At the same time, the music chip drives the buzzer to emit music.
⚡【Supply voltage】: 4.5-5V DC
🎯【Circuit principle and introduction of key components】:
🎯【1】:In the circuit, resistors R1, R2, R3 and electrolytic circuit C4 form the RC oscillation peripheral circuit of CD4060. Changing R3 can change the frequency of the oscillation circuit. The CD4060 internally counts the oscillation signal, and the counting result is output from the Q4-Q14 pins. , different count values correspond to different outputs.
🎯【2】:The pin of CD4060 is the reset terminal, which is reset by high level. This circuit selects three output terminals Q5-Q6, when the pin outputs a low level, the transistor connected to it is turned on, and the LED connected to the emitter of the transistor lights up.
🎯【3】:When Q5-Q7 are all high level, D2-D4 is turned off, and a high level is formed on RST. Pin 12 of CD4060 is reset after inputting a high level. After reset, the output terminals are all 0, so that D2-D4 are all turned on. RST goes low again from . Start counting, and so on.
🍀【DIY Soldering Kit】: It is widely used in schools to help students learn basic mechanical and electronic skills.There are many life scenarios for this circuit application, and it is a kind of circuit that circuit designers need to master.
🍀【Easy Assembly】: The connection that was clearly mapped and labeled on the board makes it easy to assemble. Even beginners can easily solder successfully.
📞【Wholesale business】:We have been engaged in the wholesale and retail business of electronic related products for a long time. Welcome letter to discuss wholesale busines
