3D Printers

[Quote: From Jed]

3D printers can print all sorts of plastics. For your application you could use PLA or PETG or ABS, I don’t think it would be necessary to do any of the really fancy stuff like Poly-carbonate, Flexables, or nylon. Here is a page with just specialty filaments [matterhackers Specialty Filament]

3d printers don’t get a lot less expensive when they get smaller. I’d recommend buying one that is a “standard” size. Right now that seems to be 200×250(8″ x 10″) or so. There are a lot of places that sell garbage as well, so you will want to be careful if you buy a kit. I’d recommend going to [prusa3d.com] and checking that out. I’ve heard good things about [cetus3d.com]

The features to look for are a heated bed that can go to 100C and a “all metal hotend”, even better if it is a genuine e3d.

I have a couple printers,

Taz 6 [lulzbot taz 6] ~2500
This one was the first one that I bought. It is fairly expensive, but it has a quite large build area(11.02 in x 11.02 in x 9.8 in). It prints quite well, and has all high quality components. It has a fairly large nozzle which limits it’s ability to print small details.

Prusa MK2S [prusa3d i3 kit] ~700
This is the one I like the best. It prints well and reasonably quickly. It has a slightly smaller nozzle than the Taz so it can do detail better.

Monoprice Maker Ultimate (No web address, as I don’t recommend it at all) ~800
Doesn’t print well without constant management. Prints slowly with that constant management.

Blinking:

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(250);

  digitalWrite(LED_BUILTIN, LOW);
  delay(250);
}

Reading from Potentiometer:

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

void loop() {
  // Read the potentiometer on analog input #0
  int sensorValue = analogRead(A0);
  // print the value
  Serial.println(sensorValue);
  // wait
  delay(1000);
}

Use Potentiometer to dim LED:

const int LED_PIN = 11;

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);

  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  // Read the potentiometer on analog input #0
  int sensorValue = analogRead(A0);

  // Use the sensor input to manipulate the delay
  int iDelay = sensorValue / 1000.0f * 5;
  digitalWrite(LED_PIN, HIGH);
  delay(iDelay);
  digitalWrite(LED_PIN, LOW);
  delay(1);
}

>> What kind of voltages does the Arduino support?

Arduino input voltages are either 3.3V or 5V depending on the version of Arduino. The Arduino can supply 150ma of 5V or 50ma of 3.3.

Control your LEDs with your TV remote?! || Arduino IR Tutorial

I created a [XamarinFormsIoT] Windows Core IoT project which can control LEDs and play sounds on a Raspberry PI 3 using C#/XAML. I used a portable dependency interface to expose the GPIO controller which only exists in the UWP project. GPIO is used to control the LEDs. I also ordered an IR receiver so I can detect IR signals from a remote and it works!

Next I need to [find] a UWP library for LIRC.

The [Arduino-IRremote] has a C++ library that can be converted to UWP.

I followed the idea from the video below.
