Goal:

  • Create a shield for an Arduino Nano that could allow us to connect our module electronic components and wear it.
  • Work on first approximations of body movement with Marc Sans.


Materials:

Conductive fabric bend sensor

Adxl335 ( usual accelerometer )

Mobile power bank

Copper sheeet

Voltage Regulator

nRf24L01+

Capacitors

2 Cell coin support

2 3.3 V Cell coin batteries


Activities:

PCB shield – design for an Arduino Nano using Eagle and then machining it, with a Roland SRM 20.
Arduino Nano + Accelerometer + Bend Sensor + ADXL335 + Power Bank

By far, the best solution for getting a nice and stable 5V input is from PowerBanks used for charging mobile phones. These devices are basically lithium batteries.
Cell coin batteries (2) didn’t work very well, as soon as they were a little bit discharged, the nrfL24L01+ stopped working.

We’ve been using a SONY – CycleEnergy with two Li-ION batteries inside & another power bank that was given to us as a present in an event from a Spanish telephone company.

For this test we used an arm band for mobile phones just to hold our circuit.
We also made a PCB using the Roland SRM-20 to create a simple shield for using an Arduino Nano.
