Emotionally – Reacting Face with MicroPython on Pulsar C6

Project Launch: A Reacting Face Powered by Movement and MicroPython

We’re excited to share Emotionally, a cute and expressive project running on the new Pulsar C6 development board. This Nano-sized board based on the ESP32-C6 supports MicroPython and is fully compatible with Qwiic I2C accessories.

Emotionally reacts to how you move it: shake it hard, and it gets angry; leave it alone, and it gets sleepy. It's the perfect example of using sensors and displays to give character to embedded systems.

What is Pulsar C6?

The Pulsar C6 is a Nano-format ESP32-C6 board designed for MicroPython, C, or Arduino. It features:

• RISC-V ESP32-C6 chip (2.4GHz Wi-Fi + BLE + Thread)
• USB-C native support
• LiPo battery management
• I2C Qwiic connector
• Arduino Nano pinout compatibility

Project Objective

Emotionally aims to create a personality-driven display that visually expresses emotions using:

MPU6050 IMU for motion sensingOLED display for face rendering

MicroPython as a reactive control engine

The project teaches how embedded systems can feel alive through minimal hardware and fun logic.

Software Setup

Flash MicroPython to the Pulsar C6.

• Upload main.py and mpu6050.py using mpremote or Thonny.
• Power on the board — the face will appear on the screen.
• Move the board and watch the expression change in real-time!

Emotions Logic

• Happy: Gentle movement
• Surprised: Moderate shaking
• Angry: Harsh motion
• Sleepy: Still (ZzZ animation included!)

Animations are drawn pixel-by-pixel on the OLED using MicroPython and custom rendering functions.

Final Notes

This project brings together sensors and displays to create an emotional and interactive device. It’s ideal for:

• STEM education
• IoT toys or wearables
• Character-like robots
• User-interface experiments
