Since then the Arduino is not detected by the pc like before, it seems like it's powered with a only power usb cable. Next day I tried hooking up the pro micro: all the LEDs were lit, no blinking the device manager said "usb device not recognized: request device descript" or something like that like when the sketch was running fine. So I decided to call it a day and went to sleep. Comes in black and white starting at 49.99. Includes HD video, motion detection, chime app alerts, two-way audio, and more. Project title: Introducing innovative changes in the design of BLINK.PRO brand measuring devices along with the development of a hybrid production station The aim of the project is to develop and implement on the market a line of innovative, significantly improved BLINK.PRO Infinity 2.0 and BLINK.PRO Diamonds 2.0 products. #Blink pro 2.0 installInstall wire-free with powerful battery life or wired to also sound your existing in-home chime. Then after some more shorting the LEDs were always turned off, except obv the power one. Experience peace of mind at your door with Blink Video Doorbell. #Blink pro 2.0 driverNo driver made it work, so I tried shorting RST and GND twice: the result was that when I was shorting those pins the sketch stopped, and the pc didn't see anything (i have to specify that the sketch interrupted only when I was shorting: even with double short as long as I interrupted the short, the blinking restarted). Hi! Thanks for the reply! After I uploaded the code to get the LEDs blink (found it on the internet for the sparkfun promicro) the Arduino was communicating with my pc since device manager said that there was a not recognized usb device hooked up (it also said "request description device" or something like that). The fact that it worked once really limits the number of possible causes! It's also possible that they set the fuses wrong, leading to the bootloader not being started when a sketch was present - in this case, reburning bootloader with an ISP programmer would sort it out (but nothing else would) But double-tap on reset button (or manually shorting RST to ground twice in rapid succession if there's no button) should fix this. The normal cause of a 32u4 based board taking an upload once only is that the sketch uploaded malfunctioned badly enough to hose the USB (writing off the end of an array for example will often do this), so no USB device would show up while the sketch was running, making it impossible to upload new code. So you were able to upload to a 32u4 based board once but only once?
