HAPPY HALLOWEEN! Each weekday this month we’ll be bringing you ideas and projects for an Electronic Halloween! Expect wearables, hacks & mods, costumes and more here on the Adafruit blog! Working on a project for Halloween this year? Share it with us on Google+, in the comments below, the Adafruit forums, Facebook, or Twitter— we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). Tune in to our live shows, Wearable Electronics with Becky Stern and Ask an Engineer, where Adafruit store discount codes are announced– get the most bang for your Halloween buck!
Analog Feedback Servo – It looks like a servo, it acts like a servo, but it’s more than just a servo! We got a factory to custom-make these classic ‘standard’ sized hobby servos with a twist – the feedback (potentiometer wiper) line is brought out to a fourth white wire. You can read this wire with an analog input such as those on an Arduino, to get the servo’s position. That information can be used in robotics to improve stability or even allow ‘recording’ of servo motion.
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
Join us every Wednesday night at 8pm ET for Ask an Engineer!
