I was testing a brand new InfraRed detector from RadioShack using LadyAda's tutorial: Testing an IR Sensor | IR Sensor | Adafruit Learning System
The pins were all hooked up exactly as pictured and double-checked on the datasheet (on the package). I was using my Arduino MEGA 2560's 5V pin to power the IR sensor. I fired off some IR signals to the device, and it didn't work. I checked the IR LED with a webcam, and I saw it working. When I felt the sensor, it was extremely hot. About 15 seconds later, my Arduino just quit. I am sure I didn't hook anything up backward. Now when I plug in my Arduino, the power light comes on, but I can't upload anything onto the board (I tried the 'blink' sketch).
Any help is appreciated. I'm not sure how to reset any fuses if there are any.
I wasn't using any Arduino code. I was just using the 5V pin as a power source. The entire setup was on a breadboard. Everything was according to the Fritzing picture on this page: Testing an IR Sensor | IR Sensor | Adafruit Learning System. The only difference was I was using the 5V pin instead of the battery packs. Some info on the problem: When I upload the blink sketch, it just says 'uploading' forever. I am using Arduino 1.0 and the status bar gets about 5/6 through before getting stuck. Thanks for any help.
I have tried Resetting the board, but nothing seems to work.
If that is all you did then there is no way that you could have damages your arduino. You must have actually done something different. Favorite is getting the sensor the wrong way round, that is the only way you could get the sensor hot.
Yeah, I think I must have flipped the sensor's pins. I think I may have to dish out and get a new Arduino. I like that Arduino Ethernet...
Thankfully I can use my LilyPad in the meantime. BTW, do you have any experience using Kinect with the Arduino?
Thanks for your help,
Joseph
(I'm also building my Freeduino 1.2 right now: can't wait for capacitors!!)
The only thing it could have fried on the arduino is the power regulator if it was only ever connected to the 5V, Unless there was some other higher voltage pumping into the 5V pin. Try and replace the voltage regulator before you bin it.
If you have a photo of your wiring and a link to the datasheet we can check our assumptions. You have to be ultra careful about pinouts w.r.t front and back as different datasheets use different views. 3D-style diagrams are always preferably in my mind. How was the Mega being powered BTW?
Sorry I couldn't get back to you sooner. Like I told @GrumpyMike, I used the LadyAda Fritzing diagram on this page: Testing an IR Sensor | IR Sensor | Adafruit Learning System. The datasheet: http://www.ladyada.net/media/sensors/PNA4602.pdf I'm pretty sure this is the sheet. I can't seem to find the sensor on RShack's website and I don't have a picture. I think I will try to change the V Regulator on my board. Thanks for all you help!!

I also only set it up, but i totally fried my sensor. It gets extremely hot, also if i switch te pins.
What am i doing wrong? pls help me
