It was supposed to be a gift for my girlfriend but right now all it does is to frustrate me. I hope that you guys can make sense of it, because I couldn't.
After that, if I want to change the threshold for the ambient light, I should be able to do that without disconnecting GND. But it is unacceptable for me, since I plan to solder all the cables together, put it inside the lamp's box and connect it to an USB charger. When I do that, connection to the PC is established. The only way to connect the Trinket to the PC again is that I disconnect the GND cable and reset it again. USB plug out sound comes, I wait for like 30-40 secs until plug in sound comes and it says USB device is not recognized. I push the reset button, still no blinking red light, still dimmed. There is no flashing light, no connection to the computer (no plug in/plug out sounds), green light is lit, red light is dimmed but there, my lamp is (which has RBG leds and changes constantly) is rebooting the pattern in every 2-3 secs.
ADAFRUIT TRINKET 5V USB CODE
But whenever I connect it to the power source (different USB chargers, I tried) system overrides the code and the lamp is always on. When all the cables are connected and Trinket is connected to my PC (Windows 10, connected through USB 2 hub) the code works.
ADAFRUIT TRINKET 5V USB PRO
Keep the UNO’s fancy USB connection with none of the size. The onboard 5V regulator can provide 150mA output, not 800mA out You cannot plug shields directly into the Pro Trinket There is no Serial-to-USB chip onboard. I wrote my code, tested the device on breadboard. Adafruit Pro Trinket - 5V 16MHz SKU: 19037. I'm adding a LDR sensor that whenever the ambient light gets below the threshold, lamp automatically turns on. This is my second Trinket project (so I am slightly familiar with it and my other project worked fine) but this time something is wrong: I am unable to upload anything to the Trinket after I connect it to the USB charger, then connect it back to the PC.įirst, my project: I have a lamp which runs on standard smartphone USB charger. Hey everyone, this is my first post and English is not my primary language, so I'll try to explain myself as much as possible.
