Hi,
Please excuse me for lack of correct terminology etc, I am a complete noob at all this.
I have recently invested in an Arduino to try to help me complete a college project, I basically need it to monitor the temperature of a surface and activate a heat element when it drops below 2 degrees celsius.
So I have got the basic concept working. At present, the system checks the temperature ....if above 2 degrees celsius it goes to sleep for a set period of time before rechecking or if below 2 degrees celsius it activates an LED (I've used that because I haven't worked out the heating bit yet).
So this is where I need the help:
1. What can I use to heat a glass surface about 1 metre x 2 metre in size?
2. How would I power it? It needs to be from a battery - as the item needs to be portable...is it possible to generate a decent amount of heat to actually heat the surface?
I imagine that the main circuit will run off a 9V battery, which with a bit of tweaking should last a good length of time.
I would then be in effect, activating a separate circuit powered by a more powerful rechargeable battery when heat is required.
Would really welcome and thoughts / suggestions
Thanks
