وحدة تعدد القنوات الأنالوجية CJMCU-4051 74HC4051 ذات 8 قنوات
تمت ترجمة جزء من المراجعة تلقائيًا.
تعبئتها بشكل جيد ومعقولة وقت التسليم (22 يوما تقويميا من النظام). تتيح لك هذه الوحدة اختيار الإدخال التمثيلي الذي يتم توجيهه إلى منافذ ADC الخاصة بوحدة التحكم الدقيقة. إنها وحدة مفيدة وواحدة أحب أن أحتفظ بها في المخزون في مختبر الإلكترونيات الهواة الخاص بي.

This is a great interface for the multiplexer chip, and very easy to use. Basically, it is a 1-to-8 or a 8-to-1. It works both ways! Essentially, you apply true/false to the S0, S1, and S2 inputs in the combination of a binary number to indicate which of the Y pins you want connected to the Z pin. Then it acts as though it has physically connected the two pins, and only those two pins, together. Power goes both ways. Simplest application: Connect each Y pin to an LED, then an appropriate resistor (440Ohm) and then to ground. Connect the Z pin to Vcc (5V). Connect the VCC to 5V and GND to ground. Connect E to ground to enable the board (high will disable it.) Then connect each of the S pins to either VCC or GND in different combinations. For each combination, a different LED will be lit. This component is best used when you have 8 outputs that can be activated one at a time, but only have 4 or 5 pins for your output. If you combine two of these boards, you can use the E pin as a fourth addressing bit, turning 5 pin outputs into 16.
good
works as expected with my arduino project
exactly what i needed
