Pressure Pack & Servo

Make and use your own pressure sensors to control a servo and LED brightness. ⭐

This kit contains supplies to make 4 or 5 sensors, depending on their size and shape. You’ll have conductive fabric and felt left over too!

Make a sensor in any shape you want — sew them into a sock on the heel for pressure when walking, into a back jeans pocket for pressure when sitting, and a lot more!

You’ll be able to use a pressure sensor to control servo movement and light an LED with altering brightness. This project is also featured in The Ultimate Guide to Informed Wearables.

Also check out the HEX Field Pack and Hattie Field Pack for more intermediate wearable kits.
