Noobie with newb questions for simple project

masterbri
masterbri over 7 years ago

Hiw are y’all doin!! So, I’ve been playing around with an arduino project for quite a while now and finally got it to work after a year of tinkering. I was working on what seemed like a fairly straight forward led matrix thing using glediator and an Arduino UNO.

 

My current project that I’ve been looking into seems a little more complex to me in that I want to actually have different systems communicating with each other. I’m sure this is kinda child’s play to yall out there that are more familiar with this stuff so please bear with me as I still consider myself quite illiterate in this field!

 

heres my situation: I have two separate objects, one is essentially a transporter and the other would be package. The transporters job is to lift the package and move it to another location. I plan to have an Arduino UNO with an rfid sheild mounted in the transporter and an rfid tag mounted on the package. The first goal is to have the transporter read that the package is near and activate a switch that drops the lifting mech.

The transporter is also outfitted with a photo sensor that triggers an audible alarm letting me know when the package is centered on the lifting mech. The second goal is the have the arduino recognize that the sensor has been triggered, say for 3 seconds, and then activate he other switch which would raise the lifting mech.

 

To me it it seems like two gairly straightforward operations. my biggest obstacle is figuring out how to write a code to handle these two distinct operations within the ide, from scratch

 

i sure appreciate any help y’all could provide!!

thanks, Brian

    Hi Brian, I'm not sure it is as straightforward as you suggest : ( The devil is in the detail. At a high level, the pseudocode is simple: while(1) { result=readTag(); if(result) { lifting_mechanism…

    Perhaps take a look at this RFID tutorial:

    Tutorial 12 for Arduino: RFID Card Reading

    It's for a door lock however it covers a lot of the elements your project requires, namely the reading of a RFID tag, operating a motor, playing an audio notification. There is a button input but in this case it is attached directly to the RFID reader enable pin rather than the Arduino so you may want to take a look at this other tutorial on using a LDR sensor with an Arduino:
