HS Augsburg, Prof. Andreas Muxel

Arduino Nano 33 IoT

• https://store.arduino.cc/products/arduino-nano-33-iot
• restart board > press white button on board once
• hard reset (if board is not visible in Arduino IDE) > double press white button on board

Grove Shield for Arduino Nano

• https://wiki.seeedstudio.com/Grove_Shield_for_Arduino_Nano/
• to work with Arduino 33 serial boards, please switch the VCC power to 3.3V. If the VCC power supply is switched to 5V, the development board may be damaged!

Seeed Grove System

• parts available in Prototyping Lab: https://github.com/HybridThingsLab/protobase/wiki/Seeed-Grove-System
• Grove Ultrasonic Ranger (tutorial & library), https://wiki.seeedstudio.com/Grove-Ultrasonic_Ranger/, see also code example /Arduino/01_sensors_to_osc

Capacitive Sensor

• Capacitive Sensor Library, https://github.com/PaulStoffregen/CapacitiveSensor
• further details principle capacitive sensing: https://playground.arduino.cc/Main/CapacitiveSensor/
• if you want to connect sensor to digital pin 2 and 3, use "D2" connection on Grove Shield for Arduino Nano
• if you want to connect another sensor to digital pin 4 and 5, use "D4" connection on Grove Shield for Arduino Nano
• never touch metal, foil etc. directly, always use another material in between (for example foam noodle etc.) for best results!
• see also code examples /Arduino/04_CapSense_to_osc and /Processing/sketch_08_CapSense_to_midi

Flex and Pressure Sensor

wiring	step 1	step 2
step 3	step 4	step 5

• measure value on analog input (for example A0)

Soldering

• check tutorial Wiki Prototyping Lab, https://github.com/HybridThingsLab/protobase/wiki/Soldering

step 16	step 17	step 18	step 19	-

• step 1: remove thin lines from 3D Printer
• step 2-4: snap switch gently to case
• step 5: prepare cables and shrink tubes
• step 6: attach cable to connector before soldering, otherwise it get to hot
• step 7: don't forget to add shrink tube to wire before soldering
• step 8-9: solder red and green cable
• step 10: heat up shrink tubes
• step 11-13: solder green and black cable
• step 14: heat up shrink tubes
• step 15-16: put cables and Arduino Nano 33 IoT into case(tube)
• step17: connect black cable to GND and red cable to VIN Pin of board
• step 18: scew cover with switch on case(tube)
• step 19: finished

Wiring multiple sensors

• GND and 3.3V of mulitple sensors can be shared when wiring
• the yellow cable (measurement) should be wired individually to port needed (p.ex. A0, A1...)

MIDI setup

• Mac: activate MIDI Port in system settings, https://support.apple.com/de-de/guide/audio-midi-setup/ams1013/mac
• PC: install loopMidi: http://www.tobias-erichsen.de/software/loopmidi.html, to have a virtual MIDI port (Processing <> Helm)

Helm synthesizer

• download: https://tytel.org/helm/
• click on logo for Audio/MIDI settings (activate virtual MIDI port here)
• set "VEL TRACK" to 100%
• right-click on knob and use "Learn MIDI Assignement", see also code /Processing/sketch_06_midi_set_control
