Hi to every one!! I this clock on alliexpres and think about a think.
Help my Grandpa if he need help.
I user adruino, nodeMCU and TTGO. How this clock Work? I think only that the clock conect to Wifi, then put a touch button. If you click 3 time, it send a help packet to a SQL Server and advice to my or others.
