Prazo de entrega razoável e bem embalado (22 dias de calendário a partir da encomenda). Este módulo permite selecionar qual entrada analógica é roteada para as portas ADC de um microcontrolador. É um módulo útil e um que gosto de manter em stock no meu laboratório de electrónica.

Well packaged and reasonable delivery time (22 calendar days from order). This module lets you select which analog input is routed to a micro-controller's ADC ports. It' a useful module and one I like to keep in stock in my hobbyist electronics lab.

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.
