Hello, I have a couple of these and was wondering if it was possible to use an LM35 (or similar) to measure the temp and then switch the pads on/off if above/below a certain temp? Totally new to electronics :)
Thank you so much!! That fixed it!! Thanks for the quick response!!
I’m having a problem with the example code for the Hand Warmer Heat Pad. This line “ mode = mode == 3 ? 0 : mode + 1;”
says “‘mode’ was not declared in this scope”.
Anyone found this out also? Thanks.
Looks like the example code was missing a variable declaration. If you add int mode; near the top, right under the int led3 = 11; line, that should fix it. The example code has been updated as well.
int led3 = 11;
