Hi guys. Busy trying to get my Eleven, lcd shield, temp sensor, rtc and 8 channel together for a project and until I get a bigger board Im using a breadboard to free up some pins. Ive been trying to use an old screen i had handy

But the board gets hot, too hot to touch. Im using a 12v adaptor to power it up
Any idea why this is

Re: Too hot
Which part of the Eleven is getting hot? Is it the microcontroller itself or the power area (bottom-right)?
In the meanwhile, double-check your wiring especially to that external LCD you're using. If possible, measure the current all your external devices are using - if it's close to 1A you need to use external power for some of them instead of all feeding from the Eleven's supply.

Re: Too hot
Its not the microcontroller but under the external power plug. Its fine with it going through the usb. But ive put the everything on a couple of breadboards and used the lcd shield. All good.
Another question, I can move it if you like as its about the temp module not the eleven, but I cant seem to locate a sketch to upload to display to lcd.
Im trying to build an aquarium controller, and several promising threads that are similar just stop.
Any help would be appreciated

Re: Too hot
Using the LCD is explained in the quick start guide:
http://www.freetronics.com/pages/16x2-l ... tart-guide
It uses the standard LiquidCrystal library which is explained in more detail and examples can be found here:
http://arduino.cc/en/Reference/LiquidCrystal
Perhaps consider a good book on Arduino that covers all these sorts of things, for example:
