Post by sidbenac »

I need to build a vibrating alarm clock wrist for my daughter that i can program with usb cable

can i just hook a vibrating motor http://www.adafruit.com/products/1201 to the trinket 3.3V usb and use it as alarm clock ?

i don't need an lcd, just program it through usb,

thank you

You can do that. Just be sure to put a resistor in series so that you don't overload the Trinket I/O pin. Try values between 100 and 1000 ohms, and see which one gives enough vibration.
