ขาย ❀ชุดไฟ Led Ne555 + Cd4017 อิเล็กทรอนิกส์สําหรับตกแต่ง 1 ชิ้น ราคาที่ดีที่สุด

Description: Material: PCB Color: blue Size: 54 * 21 mm Weight: 9G. Package name: NE555+CD4017 assembly/spare parts Power voltage: 2.5-14.5v PCB size: 5.4cm*2.1cm Features: The thickness of the PCB: 1.6 mm. This suite is mainly made up of the clock generating circuit and decimal counter circuit, running multivibrator by NE555 as the core, electricity flow through R2, R3 and R4 to charging capacitor C1, when C1 started charging as NE555 2 feet is still in a low level, so the output terminal 3 feet high, when the power supply through R2, R3 and R4 to C1 charge to two-thirds of the power supply voltage, the output terminal 3 feet level from high to low, NE555 internal discharge tube conduction, capacitor C1 via R4, R3, 7 feet discharge NE555, until C1 on both ends of the voltage is lower than one-third of the power supply voltage, N The three-pin level of E555 changes from a low level to a high level. Charging time: 0.695 (R2, R3 and R4) C1, discharge time is: 0.695 + R3 (R4) C1, adjust the R4 can control the output of the oscillator frequency, the NE555 clock oscillation signal continuously on CD4017 14 feet, in the ten CD4017 ten LED only on the output side, when CD4017 10 output in turn under the clock signal is a high level, the D1 - D10 lit up in turn, to form water light effect. The flow speed of LED lamp can be adjusted by adjusting R4.
