I studied electronics but I left it in the drawer for many years. For some time I have rediscovered my hobby and with a lot of effort, a lot of effort I am applying myself for programming arduino. Lately I discovered node red and I am passionate about the IOT of my home by building boards and driving them with a raspberry and node red. Unfortunately my studies (including the English language) are limited and conciliating free time and daily commitments is not easy but when you see the results the satisfaction is enormous.
