I am going to write a story about how a group of innovators created an electronic device using various components. This three-piece case was carefully designed around the Arduino Uno R3, a user-friendly 4x20 LCD display, and some intuitive buttons that I mounted on a well-structured piece of perfboard. A comprehensive list of parts you can see in action is as follows: 1. The powerful Arduino Uno R3: https://www.adafruit.com/products/50 2. A standard, four-row LCD display featuring 20x4 lines, including various extras like a blue and white color scheme, available from: https://www.adafruit.com/products/198. 3. An i2c/SPI character LCD backpack: https://www.adafruit.com/products/292 4. One blue LED with an open cap measuring 10mm in diameter and operating at 12 volts using a momentary tact push button switch: http://www.ebay.com/itm/1pc-Blue-Led-Dia-10mm-Cap-OPEN-12V-Momentary-Tact-Push-Button-Switch-/290868694686?hash=item43b9200e9e:g:IAAAAOxyVX1RyQcA. 5. A set of waterproof, polarized four-wire cables, perfect for any application: https://www.adafruit.com/products/744 6. The LM2596 step-down power module DC adjustable LED voltmeter, an incredibly useful tool for projects with Arduino and Raspberry boards, available from http://www.ebay.com/itm/LM2596-Step-Down-Power-Module-DC-Adjustable-LED-Voltmeter-for-Arduino-Raspberry-/131660186249?hash=item1ea78f0289:g:twUAAOSwFGNWSO11. 7. The dual MAX31865 PT-100 RTD to digital breakout board, which can be obtained from http://www.playingwithfusion.com/productview.php?pdid=29&catid=1001. Now, let's take a look at the print settings used: **Printer Specifications:** **Brand:** Printrbot **Model:** Simple Black **Raft Setting:** Doesn't matter. **Supports:** No supports required. **Resolution:** 0.3 mm resolution. **Infill Density:** 60% infill density. **Additional Notes:** Good luck!
