We have been an Adafruit reseller in the UK since 2010, stocking a huge proportion of the range including Adafruit Neopixels, Adafruit Flora, Adafruit Gemma, Adafruit Feather and more. No matter what power supply you hook to the 'Bat+' battery pin, if you hook the servo power to the '5V' pin on the trinket, the trinket's on-board 5V regulator will temporarily collapse under the load of the servo, which typically causes the system to reset over and over again.

Instead, please hook the servo power directly to the battery.Īlas, a typical partially-drained 9V battery has enough internal resistance that the battery's voltage will temporarily collapse under the load of the servo, which typically causes the system to reset over and over again.

The 'Adafruit 16-Channel Servo Driver with Arduino' tutorial says: Many people, even when they intend to eventually run their system on batteries, start out using a wall-wart power supply, so they don't have to keep wondering 'Is this glitch because of a bug in my software, or is the battery just going dead?'. 4xAA Battery Holder - 6v with Alkaline cells.4.8 or 6v Rechargeable RC battery packs from a hobby store.'How to get high current from 9 volt batteries' You might also want to look at other Battery holders that hold lots of AA batteries in a convenient package. I really like the Adafruit Pro Trinket, the 5V version is almost identical to the Arduino Uno (asides from the aforementioned pin 2 and pin 7 removal) and the Trinket Pro 3.3V version runs at 12Mhz instead of the 8Mhz of the Arduino Pro Mini 3.
