What components do I need to build Mood Cue?

You'll need 6 components: Arduino UNO, Breadboard, 10 kΩ rotary potentiometer, SG-90 hobby servo (or equivalent), Jumper wires ×6, Cardboard / paper for the mood dial face. Each comes in the matching Drishti Innovations robotics kit.

How long does the Mood Cue project take?

Around 50 minutes from wiring to working build. Difficulty: Intermediate.

What will I learn from building Mood Cue?

Use the Servo library to control a hobby servo. · Read a potentiometer and remap it with map(). · Hide noisy readings using a small dead-zone.
