挂钩许多输入Arduino的 [英] Hooking up many inputs to Arduino

问题描述

我需要帮助建立一个系统，我的Arduino和挂钩〜90的投入到它。这里是我预想的系统：

I need help setting up a system with my Arduino and hooking up ~ 90 inputs to it. Here is the system I am envisioning:

• 在Arduino是迷上了变化/钱插入机器（如在自动售货机焦支付）。

• The Arduino is hooked up to a change/money insertion machine (like paying for a coke at a vending machine).

当顾客插入的资金适量，他们可以选择他们想要激活（如自动售货机上选择不同的糖果）的设备。将有大约〜90的选择。

When the customer inserts the appropriate amount of money, they can choose which machine they want to activate (like choosing different candy bars on a vending machine). There will be about ~90 choices.

我想阿尔杜伊诺借此输入，并能够用信号通知任何个别机出来的90机器来激活一些过程中，个别机。

I want the Arduino to take this input and be able to signal to any individual machine out of the 90 machines to activate some process in that individual machine.

如何系统目前工作原理是，每台机器都有，在每台机器单独激活过程中自有资金插入机制。我想创建一个集中支付制度，它知道每台机器。

How the system currently works is that each individual machine has its own money insertion mechanism that activates the process individually at each machine. I want to create a centralized payment system that knows about each individual machine.

我的问题有以下几点：

• 是否有可能钩了90投入的Arduino再到个人信息发送到每个90投入？
  （我的研究已经使我移位寄存器，但它似乎不太可能能90个人的输入端连接到Arduino这种方式。

• Is it possible to hook up 90 inputs the Arduino and then to send individual messages to each of the 90 inputs? (My research had lead me to a shift register, but it seems unlikely to be able to connect 90 individual inputs to the Arduino this way.

有没有连接到Arduino可以接受的钱作为变革的一部分？

Is there a part that connects to the Arduino that can accept money as change?

推荐答案

有多路复用器，您可以将您的Arduino连接，从而增加其容量输入：
Arduino的游乐场复用器教程

There are multiplexers that you can connect your arduino to, which increase its capacity for inputs: Arduino Playground Multiplexer Tutorial

Sparkfun有 prebuilt屏蔽它封装复用器IC，但只给你48个输入。

Sparkfun has a prebuilt shield which encapsulates the multiplexer IC, but it only gives you 48 inputs.

至于采取硬币，设备称为硬币接收可以找到。有许多供应商，其中包括 Sparkfun 。

As for taking coins, a device called a coin acceptor can be found. There are a number of suppliers, including Sparkfun.

有可能的方式可以减少所需的输入和/或输出。例如，你需要90按钮，或者你可以使用一个10键键盘，并给予每个​​项目两位数code？

There may be ways you can reduce the necessary inputs and/or outputs. For example, do you need 90 buttons, or could you use a 10 key pad, and give each item a two digit code?
