This week on Community Corner, we used the “search” function within the G+ Community to see all of the recent tutorials our community members have been creating and sharing about the ULN2803.
Check out the video on YouTube.

ULN2803: 8 Channel Darlington Driver (Solenoid/Unipolar Stepper) – ULN2803A: Bring in some muscle to your output pins with 8 mighty Darlingtons! This DIP chip contains 8 drivers that can sink 500mA from a 50V supply and has kickback diodes included inside for driving coils. This will let your little microcontroller or microcomputer power solenoids, DC motors (in one direction) and unipolar stepper motors. Please note, this is an ‘open collector’ driver – it can only be used to connect the load to ground and there will be a 1 Volt (or more) ‘drop’ across the internal transistors. The inputs can be driven by 3.3V or 5V logic. Fits nicely in any breadboard or perfboard. (read more)
Each Wednesday on Community Corner, we share something we have enjoyed the previous week on the Adafruit Google+ Community site “Makers, hackers, artists & engineers: Learning and sharing with Adafruit!” (Note: Google+ login required.)
If you haven’t joined us at this public community yet, stop on by for a visit. And bring something to share!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
