PT Tinker is a hands-on community meetup open to all of those interested in building things with microcontrollers and single board computers. Bring an idea and your Arduino, Raspberry Pi, BeagleBone, or whatever your favorite flavor of microcontroller might be, or contribute to an ongoing group project. This meetup is a great way to get started with Arduinos and to learn from your peers.
Meetings will generally be every third Thursday of the month.
