I work at an ornamental plant nursery. Here we have something akin to an assembly line where plants are produced. People stand at stations and complete repetetive tasks in order to create the plants that we grow and sell. Our objective is to get better at tracking individual output during this process. What I want to do is create a device that is present at each work station. This device will combine a stopwatch with a push-button counter, and have the Arduino log the values for each. The logs will then be exported for use in a spreadsheet.
Here's a rough sketch (not a technical diagram) of what I imagine the device will look like, along with some notes on functionality: http://imgur.com/HsdVV0H
And here's how I envision the device operating:
- There's a master on / off switch. Turning the device off then on again will reset all counters.
- Pressing the start button gets the timer running.
- Pressing the stop button pauses the timer. Pressing start again resumes the timer. The stop button will also trigger a red LED to pulse to alert workers that the clock is not running.
- Pressing the counter button will cause the counter display to go up in increments of one. Pressing the counter button while the device is in stop mode will not affect the counter.
- At the very least, total elapsed time and the number of button presses will be logged by the Arduino for use in spreadsheets elsewhere.
On a scale of 1 (easy) to 10 (what was I thinking?), how difficult do you guys think this will be? Have you encountered any other similar projects I can look to for guidance? Thanks in advance for the help!
