An art installation that uses plants as switched to run gifs on raspberry pis
Running on Raspbian Jessie with PIXEL, Raspberry Pi B+ 16GB SD card (6) Adafruit 5pad touch sensor Wiring https://learn.adafruit.com/capacitive-touch-sensors-on-the-raspberry-pi/wiring NB: Copper wire from 5pad to plant is flat copper tape 10cm long. Longer wire makes it too sensitive.
Initial programming taken from https://learn.adafruit.com/capacitive-touch-sensors-on-the-raspberry-pi/programming-5-pad-momentary
NB: I followed this to set it up so that the 5pad.py script runs on boot https://raspberrypi.stackexchange.com/a/57560
QUOTE:
"For the past month or so I've been working on basically the exact same thing, so I've researched how to do this a lot and know how to do it with the latest version of Raspbian (PIXEL).
nodm is a minimal display manager that bypasses loading LXDE, and openbox (which is already installed on the Pi) provides a minimal session manager and works with the X server.
To set up this environment in Raspbian, install nodm with apt-get and edit the file /etc/default/nodm. You need to set the option NODM_ENABLED to true and NODM_USER to pi (or whatever your username is).
Then create a custom Xsession file in your home folder (/home/pi/.xsession) with the following contents (the while loop isn't necessary, it just automatically restarts the Python script if it crashes):
BEGINS
#!/usr/bin/env bash exec openbox-session & while true; do python3 /home/pi/Documents/script.py done
ENDS"
