Yeha, nice. Do you use BT? Or Wifi? I want to control it later over Wifi. I don´t want it start
too complicate, because i have other project, too. So i decide to use parts that i have, cheep, and for faster developing use better asia modules. The 1 and 2 version will not have feedback to controller, but for future it will be a good thing to work with Led.

oh cool! I did this too, but with transistor switches rather relays. It works really nicely, but a suggestion I would give is to wire something up to the led too. I would do this if I re-made it. With that you could see when it is ready. It flashes as it is charging, and it's when it goes solid that it's ready to press the next button. you can time it, but if it has already done one cup it boils much faster so the time is wasted
