Two years ago I did an artist residency at ITP and created One Amongst Many with then-students Christina Dacanay and Tina Rungsawang. This was our original project video:
For the second iteration I wanted to solve

Blockers for ordering parts:
Can't find IMU with exposed pinsNot sure if there's SMD version for photoresistor?Considerations / parts for rechargeable Lipo battery
Questions
- How to solder and upload code to SMD ESP32? Upload via MicroUSB?
Prototype
ESP32 board: need to press BOOTLOADER button as code is uploading
Followed this video for hooking up ESP32 to PAM8302 amp and speaker, which is based on the DacAudio library and tutorial from XTronical. Unfortunately, I couldn't get it to compile for the ESP32 board (DevKit v1) that I had. I found another library, ESP8266Audio, that I had the same issue with.
So I decided to take a step back and work on something I knew how to do: phototransistor aka. analogRead(). Just to make sure, I followed this instructable for ESP32 and got it working:

Next I hooked up the accelerometer (Sparkfun ADXL345) following the corresponding guide.
