My name is X, and I have been encouraged by you to apply forto the PhD program. I submitted my application about three months ago, but its status is still pending. Since it has taken a long time, I am trying to learn some supportivesupporting materials by myself. Currently, I'm trying to learn how to use Arduino boards, but I'm a little bit uncertain about which software to learn next. Would you please give me some advice on what software I should learn so that, if I get accepted forinto the PhD program, I wouldwill be better prepared?
