My last posting detailed getting my Arduino displaying a temperature sensor on a LCD. That worked fine. Soon after that I took delivery of a Netduino. A Netduino is … well … to quote from http://www.netduino.com/:

Netduino is an open source electronics platform using the .NET Micro Framework. Featuring a 32-bit microcontroller and a rich development environment. Suitable for engineers and hobbyists alike.

It’s basically an Arduino that you program via the .NET language. I’ve not used Microsoft languages for yonks, so why buy one of these things? Well, I’ve not used Microsoft languages for yonks. Might be fun to play with them again. Maybe Smile.

So my plan was to take what I’d done before, but this time, put the temperature sensor on the Netduino and transmit the data to the Arduino (using the RF link transmitter and receiver shown at http://is.gd/f4n3Q), and the Arduino LCD would display it. I spent quite a few hours working on it last Friday evening. A lot of pain was caused by learning some basics of .NET and C# (many thanks yellowduino on the #arduino irc channel). I fiddled with it relentlessly Friday evening and bits of Saturday and Sunday. I stopped trying to transmit the temperature and instead just worried about transmitting a set string.  But I just could not communicate from the Netduino to the Arduino.

Not quite true. I could see things ‘changed’ when I switched the Netduino on – the data on the arduino might show signs of seeing something. But what i was actually transmitting from the Netduino was never displayed on the Arduino LCD. I switched anything that could possibly interfere off but nothing. Eventually, Sunday evening, I gave in. I really didn’t mind that much, I learnt a lot and that, rather than the accomplishment, was important. But still …

This Friday evening I switched it all back on again and it worked first time. First time.

  1. Could you please post the Netduino/Arduino Code you used with the RF modules for transmitting the string? I can’t seem to make them work..

    1. Hi, Can you indeed post your RF code, I am looking for this as well? Much appreciated!

  2. What i do not realize is in truth how you’re now not really a lot more neatly-preferred than you might be right now. You are very intelligent. You understand therefore significantly on the subject of this matter, produced me individually imagine it from numerous various angles. Its like men and women are not interested until it’s one thing to do with Girl gaga!
    Your individual stuffs outstanding. Always maintain it up!
