hmm, I thought this would work, it kind of is it seems, although when the temp was climbing it turned on once for no reason, same thing just happened as it was dropping. I think I it's not comparing the time properly or something.

Abgesehen von den schon genannten Problemen kannst du im Eingang, sofern die beiden Regler nicht zu weit auseinander stehen, statt 2x 100µF auch 1x 220µF oder 1x 470µF nehmen. Bei avisierten 0,5A - 1A würde ich die eher großzügiger dimensionieren, eben...

I understand the use of power supply decoupling,but  across which chip should I place a ceramic capacitor and of what value?
Accross every chip and 0.1uF

so you suggest i just put a 6V battery to my arduino and a resistor of course to get down to 5V and supply
No!!!
Who remotely suggested that? That is very bad and will not work.

Aspetta, quindi il cavo rimarrebbe sempre sotto tensione, anche se in remoto non ci fosse nulla connesso ? (avevo capito che lo usavi per alimentare qualcosa in remoto, ma spegnendolo in locale, errore mio smiley-razz) ... in quel caso si, basta una lampadina d...

What you need is a CPLD shield for the Uno.
I would suggest that this is the last thing he needs. It is more of a throwback and it puts him outside the sc...

1) I downloaded and installed the new Tiny Core 2 (a little headache before to understand that you named the file boards.txt to another thing...  smiley-wink ). Then I used it to set the fuses to 8 MHz. Then I compiled and uploaded the BlinkWithoutDelay sketch....

Maybe make the image name a variable, and add a counter so that it increases it every time it loops to upload an image?

Hm, löten ist gar nicht so leicht. Man muß sehr viel üben. Der Lötkolben sollte 30 Watt haben. Als Lötzinn nehme ich bleihaltigen, da sieht man besser kalte Lötstellen. Durchmesser 1 mm. Ach ja, es sollte Elektronik Lötzinn sein. Nicht der aus dem Baum...

Hi Firashelu,

What you need is a CPLD shield for the Uno. CPLD's typically have dozens of Digital I/O's. You can configure these any way you like. You will have to learn a little about HDL coding. But, Verilog is very similar to the C language. For add...
