So for this weeks challenge we were told we had to make a die, a digital die.  This was a cool project. At first I just used a line of LEDs to show what number that you had but then I thought I should probably make it look like a real die so I thought I would rewire it and make it look like a real die.  So here it is. So that was my first attempt the code for that one looked like this... int pinLed1 = 12; int pinLed2 = 11; int pinLed3 = 10; int pinLed4 = 9; int pinLed5 = 8; int pinLed6 = 7; int buttonPin = 2; int buttonState = 0; long ran; int time = 1000; void setup () {   pinMode (pinLed1, OUTPUT);   pinMode (pinLed2, OUTPUT);   pinMode (pinLed3, OUTPUT);   pinMode (pinLed4, OUTPUT);   pinMode (pinLed5, OUTPUT);   pinMode (pinLed6, OUTPUT);   pinMode (buttonPin, INPUT);   randomSeed(analogRead(0)); } void loop() {   buttonState = digitalRead(buttonPin);   if (buttonState == HIGH){   ...

SO this weeks challenge was to make a multi LED count down to some even.  I chose my event to me a RGB-LED go through the entire spectrum of it's colors.  So here is the code.  I spliced a lot of the code from the example that our teacher gave us and then added my own. So here it is... const int RED_PIN = 9; const int GREEN_PIN = 11; const int BLUE_PIN = 10; int red_LED = 13; int yellow_LED = 12; int green_LED = 8; int knob = A0; int DISPLAY_TIME = 10; void setup() {   pinMode(RED_PIN, OUTPUT);   pinMode(GREEN_PIN, OUTPUT);   pinMode(BLUE_PIN, OUTPUT);   pinMode(red_LED, OUTPUT);   pinMode(yellow_LED, OUTPUT);   pinMode(green_LED, OUTPUT);   } void loop() {   //int displayTime = analogRead(knob);   digitalWrite(red_LED, HIGH);   delay(2500);   digitalWrite(red_LED, LOW);   digitalWrite(yellow_LED, HIGH);   delay(2500);   digitalWrite(yellow_LED, LOW);   digitalWrite(gre...

So this week was a bit more challenging in fact I never got it to work exactly the way that I wanted to despite several days of trying and failing.  I guess I just found a whole ton of ways to not make a led get brighter with a variable resistor. Anyways the goal this week was to make a LED brighter by wiring a analog input from a variable resistor.  So anyway maybe there is someone that will read this blog and help me to understand why it didn't work the way that it was suppose to. So here is the code that I used to make this project try and work. int led= 13; int knob = A0; int output = 0; void setup() {   pinMode(led, OUTPUT); } void loop() {   int val = analogRead(knob);   output = map(val, 0, 1023, 0, 255);   analogWrite(led, output); } Here is a video of it "working" So as you can see from that video that it didn't work as intended so I thought I would play around with it for a while.  It took me several days of changing the...

So this is the first project in my new class called makerspaces. I am really excited to get into exactly what a makerspace is and how I can use one or have a mini version of one on my campus perhaps. So the first project is to use this tiny controller called a arduino uno to make and led blink. It is a pretty simple circuit with a resistor and an led in series with the controller. You then type the code that is below in the arduino program software on you computer and then you upload it to the arduino uno using a USB cable and then there you have it your led starts blinking. It is actually really cool but very simple to do. This is the schematic that I used to design the circuit. This is what it looks like in real life. Here is a little video of me explaining my project. There really wasn't too much trouble with this project. It worked the first time that I plugged it in. the only thing that I did for trouble shooting is I plugged the LED straight into...
