<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p><strong><span style="font-size:20px">Features: </span></strong><br/>1. This kit is a music colored light electronic kit that combines surface mount and direct insertion components. It is composed of high-quality electronic components, with stable product performance and long service life. <br/>2. High quality fiberglass fiberboard, PCB board directly printed with component identification, reasonable wiring, compact component layout, and convenient welding. <br/>3. Using CD4060 as the control chip, the music chip emits music after power on, making it convenient to use. <br/>CD4060 controls the red, yellow, and green LEDs to flash along with the music, and adjusting the potentiometer can adjust the speed of LED flashing. <br/>5. The kit can be used for practical training in electronic technology fundamentals and skills teaching, electronic skills teaching, electronic process teaching, digital circuit teaching, and practical training for electronic enthusiasts and beginners to enhance comprehensive practical abilities.</p><p><strong><span style="font-size:20px">Product Description: </span></strong><br/>A 14 stage binary counter CD4060 with an internal oscillation circuit is used as the control chip to control the flashing of 12 red, yellow, green L prints and D. Adjusting R3 can change the speed of LED flashing, while the music chip drives the buzzer to emit music. In the circuit, resistors R1, R2, R3, and electrolytic capacitor C4 form the RC oscillation peripheral circuit of CD4060. Changing R3 can change the frequency of the oscillation circuit <br/>CD4060 internally performs pulse counting on the oscillation signal, and the counting results correspond to different outputs with different counting values output from pins Q4-Q14. The pin of CD4060 serves as the reset terminal for high-level reset. This circuit selects three output terminals Q5-06. When the pin outputs low voltage, the transistor connected to it conducts, and the LED connected to the transistor emission calibration lights up. When Q5-07 is at a high level, D2-D4 is cut off, forming a high level on RST. The 12 pins of CD4060 input a high level and reset it. After resetting, the output terminals are all 0, making D2-D4 conductive. RST becomes low and starts counting from 0 again. This cycle continues.</p><p><strong><span style="font-size:20px">Parameter: </span></strong><br/>Product Name: SMT Music Lantern Experimental Kit <br/>Material: FR-4 fiberglass board <br/>Chip: CD4060 <br/>Voltage: DC4.5-5V <br/>Size: 75mm * 45mm <br/>Potentiometer: Adjust the speed of LED flashing <br/>Purpose: This kit can be used for teaching and practical purposes in related fields and for professionals to use</p><p><strong><span style="font-size:20px">Package include: </span></strong><br/>1X diy kit</p><p>Attention: This product needs to be welded by the customer themselves, and shipped as loose parts, not finished products!<br/></p></div></div><p><br/></p>
