I did a very similar project for home automation in college; unfortunately I don't have the files/code anymore. I used Arduino, several sensors and actuators, and the touchscreen display. Here's some information about the display:

The company 4D Systems offers a wide range of Arduino compatible touchscreens up to 7" - [https://www.4dsystems.com.au/products]. The displays can talk to Arduino using different communication protocols, such as Serial, I2C, and SPI. Some fairly simple examples along with code and step-by-step instructions can be found in their website - [https://www.4dsystems.com.au/appnotes]. A specific example is this very simple "Hello World" application - [https://www.4dsystems.com.au/downloads/Application-Notes/4D-AN-00092_R_1_0.pdf]. An advantage is good documentation and excellent customer support from 4D Systems; but there are also disadvantages:
*Proprietary software (but still "gratis") is needed to program the display. The software is not available for Linux.
*Displays are relatively expensive (capacitive touch, ultra bright display with bezel full kits are $99 - $200).
*Some known issues with the micro SD card holding the image files in some of their products; the files can get damaged after ~50,000 read cycles, so there's a need to format and re-write the files every now and then. They supposedly improved this by using "Industrial Grade" micro SD cards. I noticed an improvement, but it didn't fix the issue for good.

I recently used this combination (Arduino + 4D Systems display) for an industrial automation project as well; if I find the files/code this week, I can upload to Github and post the link as an example that goes beyond what you would find in the links I posted.

3.2" LCD library for Arduino - [http://www.rinkydinkelectronics.com/library.php?id=51]

Hi,

We have recently built the Seed Eco-Home - see our Kickstarter from last year:
https://www.kickstarter.com/projects/622508883/open-building-institute-eco-building-toolkit

We are implementing a monitoring system for its off-grid utilities. We would like to implement an Arduino-based monitor that shows water, power, and bio-digester gas levels.

Would you be interested in helping us as a subject matter expert - in developing this Arduino-based monitoring system?

Thanks,
Marcin

OSE Development Priorities

ACenTe: /* Key Milestones for 2018 */ change a typo (cpmferences -> conferences) and removed 2 dots at the end of list elements to keep consistency throughout the list.

{{Hint|This page is required reading for all individuals who are considering becoming OSE Developers. If you would like to apply, see [[OSE Developers]].}}

=Key Milestones for 2018=
*Develop Immersion Training, deployed Sep 1 Back to School on the [[Open Source Desktop Microfactory]].
*Tuition pays for infrastructure improvements + SME contributions and freelancers to produce high quality curriculum to OSE standards
*Deploy HeroX
*Continue OSE Devs recruitment
*Develop HR capacity
*Develop SME capacity
*Develop D3D website as first distributive enterprise, including marketing
*Pivot to Design/Build from Extreme Build -
*Marketing development for steady filling of workshops: design workbench, design contests, conferences. [[Marketing Strategy]]
*Develop proposal for: R&D, Machine Product, Education Product, Workshop Product, Marketing Plan

=Key Milestones for 2017=
The work of OSE for 2017 involves 4 major milestones, for which we are recruiting collaborators:
*Q1: Developing the 3D Printer as a full release
*Q2: Extending the 3D Printer construction set platform to produce a CNC Oxyfuel Torch Table, which can be used to cut steel for building OSE's heavy machines
*Q3: Applying the CNC torch table to build the next iteration of the tractor, backhoe, sawmill, and other construction-related machines
*Q4: Applying the OSE construction machines in the second iteration of the [[Seed Eco-Home]].

=Recruiting=
*Our current state of staffing is focused on recruiting volunteer developers for dedicated project teams.
*We are currently recruiting [[OSE Developers]], Documenters, HR Generalists, and IT Generalists.
*See [[OSE Developer Job Description]] + [[OSE Documenter Job Description]]

=Contributor Requirements=
We are looking for individuals with a basic requirement of (1) downloading and using the [[OSE Linux]] distribution for development work; (2) keeping a work log on the OSE wiki (see example such as [[Marcin Log]] to promote open collaboration with a large distributed team; (3) learning FreeCAD to produce 3D CAD, which is one of the central activities involved in OSE work. We allot a 2 week learning period for candidates to study [[FreeCAD 101]], and to pass a basic [[FreeCAD Competency Test]].

=Roadmap Narrative=

The rationale of the OSE roadmap is to provide financial bootstrapping for OSE growth, and to push forward the OSE prototyping agenda aggressively:
*The 3D printer is aimed at replication as a Build Workshop Enterprise (see [[OSE Workshops]] for sample workshop offerings) - where people pay for an immersion experience. The goal is producing 12-100 3D printers in a single workshop, where people have the option to take a finished 3D printer with them. OSE is currently developing this as a stable funding model for its operations, while making this replicable by others by keeping all of the supporting assets (designs, organizational assets) free and accessible to the public. The financial concept is attracting 12-100 participants per event at $300 above the Bill of Materials cost = $3600-$30000 revenue per event. Our key for achieving this is using the [[Extreme Manufacturing]] model of 1 day swarm builds, and developing outstanding product (machine + process + enterprise) and extreme organizational efficiencies that attain [[Viral Replicability Criteria]]. This is intended to become our first [[Distributive Enterprise]].
*The CNC torch table is a natural extension of our 3D Printer Construction Set, and a powerful tool necessary in rapid manufacturing of other OSE machines. The logic of releasing both the 3D Printer and the CNC Torch Table is to help other OSE developers to engage in rapid prototyping as part of the OSE collaboration.
*The CNC Torch Table facilitates rapid prototyping of all of our construction machines.
*The construction machines in turn facilitate incremental improvement of the Seed Eco-Home, with our next milestone being to produce lumber, block, and plumbing fittings from local and recycled materials. This would bring the materials cost down significantly.

=Workflow Overview=

Development work at OSE involves a technical skill set. We encourage not only engineer types to work with us - but also anyone else in the arts, humanities, and sciences who is interested in diversifying their skill set. The main requirement of OSE Developers is a willingness to learn - as the skills required for participation are learnable in 2 weeks for basic competencies, of which there are several. The basic skill set required is computer literacy, with the ability to learn FreeCAD and other open source tools. Besides this, anyone with a high-school physics equivalent background should be able to participate. Part of our work involves bringing our contributors up to speed in widely-applicable technical competencies. Part of our work is producing high quality, 5 minute, video [[OSE Crash Course]]s on key skills to facilitate this learning.

Much of our work involves 3D CAD. A common activity is drawing up 3D CAD models from scratch, as in our [[FreeCAD 101]] tutorial. However, a great part of our work - which is based on modularity - includes using existing 3D files. This means that at the minimum, a contributor needs to move, rotate, copy, and manipulate objects in 3D - a skill that is attained readily. Using 3D files from the [[OSE Part Library]], or downloading parts from various sites - allows a novice to generate technically-correct assemblies, all using open source tools. As such, the OSE development process is accessible to just about anyone, anywhere in the world that an internet connection is available.

Most of our work involves remote design collaboration.
