Does the procedure of holding the reset button while uploading the sketch has to be repeated for all the sketches in the future or just a single one. Also, isn’t there any permanent solution to this problem. This seems to be resurfacing too often these days with a lot of sketches and apparently a lot of people. I read somewhere on another forum that it may be due to an unregulated power supply as to which the board is going into some power save mode. They posted a solution of connecting a 4.7 micro farad capacitor across the Vin and Gnd pin. It did work for some time but the old problem started all over again. Does itt just means that we can’t use these boards anymore or is there a bug or something which needs fixing? Whatever the reason be, it has affected a lot of projects.
