Tell us about yourself!
Dear Deba,thanks for your great work! About your "which Arduino"-question: I used an arduino in another solar-related project before, but then found out how easy it is to simply replace it by using a normal microcontroller - if you use the ATMega328p or alikes, you are using the same µC like an Arduino, but pay only a fraction, and you can also still use the Arduino IDE if you prefer that. There are some great articles on this "Arduino to Breadboard"-called matter.Besides that, I would love to learn more about your work, I might actually come to India in the next couple of months, but definitely to Bangladesh - let me know if you want to have a coffee (where are you based?) Best,Steffen
