arduino nano extended i/o pins by ldmicro (by Mohamed Zedan)
hello everyone i use ldmicro to program arduino uno in a project and need more i/o pins how can i add more pins ?

You can't extend pins...

Change your arduino uno for an arduino mega, with many more IOs ?

Si quieres mas entradas las puedes hacer multiflesadas.
con las analógicas coloca resistencias para variar las tensiones
ejemplo: si mayor de x haces activa Relé interno (R0) esto ya será una entrada y podrás hacer tantas como quieras eso si según programa ocupan mas memoria. un ejemplo imagínate un ascensor que tenga 10 llamadas podríamos hacerlas por una entrada Analógica.

con entradas digitales:
imaginamos que tenemos 3 entradas y las llamamos X1,X2,X3.
x1 ya es una entrada x2 es otra entrada x3 es otra entrada X1+X2 es otra entrada x1+x3 es otra entrada x2+X3, es otra entrada X1+X2+X3 como podrás ver de 3 entradas que tenemos tendremos 7 entradas digitales.
Nota Para hacer esto tendremos que colocar diodos ejemplo 1N4148
antes de los pines del Micro procesador.

si quieres mas información pídela por esta misma vía.
If you want more tickets you can make them multiflended.
with the analog ones it places resistances to vary the tensions
example: if greater than x you activate the internal relay (R0) this will already be an input and you can do as many as you want if, according to the program, they occupy more memory. an example imagine an elevator that has 10 calls we could make them through an analog input.

with digital inputs:
Let's imagine we have 3 inputs and call them X1,X2,X3.
x1 is already an input x2 is another input x3 is another input X1+X2 is another input x1+x3 is another input x2+X3, it is another input X1+X2+X3 as you can see from 3 inputs we have we will have 7 digital inputs.
Note To do this we will have to place diodes example 1N4148
before the microprocessor pins.

If you want more information, ask for it this way.

You can use 74595 for output and 74165 for input

entradas y salidas (by Calubert)
Adjunto como se pueden hacer tanto entradas como salidas en LDMicro el programa que hizo por Magdy Gamaan anterior comentario es por cuenta vueltas solo se tiene 1 entrada (solo se coloca un sensor), en este son sensores individuales uno por entrada.

es otra forma de programación y la verdad que hay varias que yo conozca.


I enclose how both inputs and outputs can be made in LDMicro, the program made by Magdy Gamaan, previous comment, is for lap counter there is only 1 input (only one sensor is placed), in this there are individual sensors, one per input.

It is another form of programming and the truth is that there are several that I know.
