Arduino

Hello!
I sometimes work with Arduino. It is an open-source microcontroller platform programmed with c++. You can do many things with it. I personally think that it is a great educational tool for electronics and programming. Their website is http://www.arduino.cc/. Recently, I have successfully put together a small project using Arduino. It uses an infrared receiver (designed for receiving IR remote signals) to record an IR signal from a remote, and stores it in the Arduino EEPROM. It can store up to 9 signals at a time. With a press on a button, it can resend that signal using an IR LED, making the Arduino usable as a crude universal remote. However, different appliances use different wavelengths and carrier frequencies, so it cannot control everything. However, I have sucessfully immitated the eject signal and power signal of an OPPO DVD player. I made a video.

Re: Arduino

One of my friends said he would try hosting a server with it. It seems pretty cool.

Uh, that wouldn't really work. The thing only runs at about 4-12Mhz, and is more oriented towards controlling raw I/O, and not high-level stuff like HTTP (or file) servers. It is still possible, but not with just the onboard memory.


@topic: I don't have an Arduino, but I have something similar (Parallax Propeller Demo Board).  The Propeller chip is more powerful than the chip on the Arduino (Atmel AVR series), with 8 cores running at 80Mhz, but can't control as much memory.

Correction: most Arduinos run at 16MHz.

I've seen people use Arduino to send messages to Twitter, and receive messages from websites. I'm not so advanced into Arduino.

Re: Arduino

Oooooh arduinos!
Happyhappyfunfun
I have one. I need to use it more though.

Someone on thingaverse made a "arduino grande", a laser cut arduino about 16x original size. If you wire in a real arduino, it actually works  smile


bye 1.4, we all loved you. but we all outgrew the site. 2.0 is a welcome change.

Ok, I didn't know the exact speed, I just knew the AVR chips generally run at 20Mhz or lower.

I have seen them do that too, but a server takes alot more memory than sending a message to one.  tongue
