Day 14: (Mon Oct 20, Week 9) Motor Drivers

Notes for 2025-10-20.

Notes from Day 13

We left off with the formulation of two design ideas:

• musical marble run

• modular wind instrument

New Assignments

The immediate next steps are to clarify the specifics of the approach and start identifying required materials.

• Due Wednesday: Prototype Bill of Materials, please submit to the first phase project documentation folder at Project Phase 1 Folder.

Agenda

1. Welcome back!

2. For the first part of class we will have a hands-on workshop to explore using a dual H-bridge motor driver to create programmed movements of a DC gearmotor. Each student should set up their own test working in collaboration with their partner.

   • Sample TB6612 Motor Driver Circuit

   • tb6612 module

   • Pololu TB6612FNG

   • brief theory of the H-bridge

   • voltage and power considerations

   • solder pins onto the driver

   • set up a breadboard circuit

   • set up a Python sketch

3. Towards the end I’ll confer briefly with each group about plans.
