Thinkabit Curriculum Exercises

We'll enjoy having you work through our curricula before we take the next steps for sharing them widely.

1. This is the outline for our Robocrafting Lab traffic light and servo motor exercises most of you have done previously - https://goo.gl/n5wh9m 
   
2. Here is a page where we're developing a few dozen diffeent exercises, listed progressively: https://goo.gl/wD21CL  

Barry's Introduction to Programming

Serial input - Unlock the door for person b

/*Using the small servo in pin 6, power in VIN, and black wire in GND
* wire for red LED in pin 13, wire for green LED in pin 7
*/

// Wei's demo of if-else-if statement, plus a Servo door lock!
#include<Servo.h>
Servo DoorLock;

void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
pinMode(13,OUTPUT); //The led is in PIN 13
DoorLock.attach(6);
Serial.println("WELCOME !");
}

char who=0;

void loop() {
  // put your main code here, to run repeatedly:
Serial.println("who are you?");
if(Serial.available()>0){
who=Serial.read();
}
if(who=='a') {
digitalWrite(13,HIGH);

digitalWrite(7,LOW);
delay(500);
Serial.println("person a wants to enter the building");
}

else if(who=='b') {
digitalWrite(7,HIGH);

digitalWrite(13,LOW);

Serial.println("person b is allowed to enter the building");
DoorLock.write(90)
delay(2500);
DoorLock.write(0);
}

}

Serial input and monitoring - Who's at the door?

// Wei's demo of if-else-if statement.

void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
pinMode(13,OUTPUT); //The led is in PIN 13
Serial.println("who are you?");
}

char who=0;

void loop() {
  // put your main code here, to run repeatedly:
if(Serial.available()>0){
who=Serial.read();
}
if(who=='a') {
digitalWrite(13,HIGH);
delay(500);
digitalWrite(13,LOW);
delay(500);
Serial.println("person a wants to enter the building");
}

else if(who=='b') {
digitalWrite(13,HIGH);
delay(250);
digitalWrite(13,LOW);
delay(250);
Serial.println("person b wants to enter the building");
}

}

Serial monitoring for Arduino sketches

Open Arduino, then use FILE, NEW.

Select and replace that template with the following.  Colors will appear automatically.

=====================================


#include<Servo.h>
Servo HokieServo;    // My first servo is named HokieServo

void setup() {
  // put your setup code here, to run once:
HokieServo.attach(6);
Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
HokieServo.write(45);
Serial.println("\t  Speed is 45 - left, medium speed");
delay(1000);
HokieServo.write(135);
Serial.println("\t  Speed is 135 - right, medium speed");
delay(1000);
}

IBM’S CALL FOR CODE PRIZE GOES TO A TEAM WITH ‘CLUSTERDUCKS’

Buoys equipped with a low-frequency Wi-Fi network could provide a lifeline to people in areas struck by natural disasters.

PROJECT OWL/IBM

YOU KNOW WHEN you try to go online at a Starbucks or on an airplane, first you get a little popup that asks you to accept some terms before you can get to the internet? That popup window exists in a sort of netherworld between actual internet connection and being offline–you pick it up via Wi-Fi, but until you click a box, you’re not actually online. A team of five developers realized in that gray area was potentially a huge opportunity to save lives.

It’s an intractable problem during natural disasters: telecommunications networks and power grids are often damaged or overwhelmed; without them, first responders struggle to help survivors, coordinate evacuations, and even count the dead. Project Owl proposes an elegant solution: an AI-powered disaster coordination platform paired with a robust communication network that can
