I have a box of random resistors. They have existed like that before I started my job so maybe students left them there? My students construct a voltage divider can calculate resistance in arduino and display the value on an LCD. They're learning color code and using multimeters at the same time.
Just sharing my experience. Anyone interested to respond feel free to chime in. Arduino is just a part of their labs. They have regular labs like op-amps, diodes, transistors etc.My students are science and engineering majors (non-ECE). Many took C or Matlab programming in the past, some in the distance past and most of them don't even touch programming in other classes. The other half never took any programming class. I created some tutorial videos and documents. After a tutorial session they started to be able to mess around with pin 13 led and character LCDs. Then a week later they finished their first mini project, a resistor sorter. They helped me sort a big box of random resistors (~150 resistors were returned to their bins). I think having an assembled shield helped a lot on the LCD. I don't think my students can survive 12 connections between the LCD and Arduino. Plus, there's two sections. With a shield, each section has their own shields so they don't have to disconnect anything after their section is over. They can always come back on a different day and finish their work. My next goal for them is to do a temperature display with min and max. Then they will work with digital inputs like buttons and eventually build an interactive temperature logger.
...Yes, if you use my shield you don't have to have the ugly wires on the LCD or fighting for space on the real time clock. If you don't need the 6 buttons on my shield, you can use their I/O pins for camera triggers and etc...Just received the PHI-1 shield kits; now just need time to get soldering! They look very good for a couple of projects in the Workshop I am teaching.. One is a Temperature/GPS data logger, the other is the Camera Controller I mentioned.. More when I get stuff assembled.This is a very nice design, John... Impressed!
