Ultrasonic Sensor Code
This was developed by Washington-Lee (Drexel) intern Sam Muscovitz:
//defining the output and input pins
#define echoPin 7 //for reciving the sound waves from the ultrasound sensor
#define trigPin 8 //for outputting sound waves from the ultrasound sensor
#define LEDPin 11 //for turning on the LED
int maximumRange = 200; //if the ultrasound sensor detects an object within the range of these two variables, it will display the object's distance
int minimumRange = 0;
long duration, distance;
void setup() {
Serial.begin(9600);
pinMode(trigPin, OUTPUT); //sets the trig pin to output
pinMode(echoPin, INPUT); //sets the echopin to input signals
pinMode(LEDPin, OUTPUT);
}
void loop() {
digitalWrite(trigPin, LOW); //outputs a voltage of 0V to the trig pin
delayMicroseconds(2); //delays the arduino for 2 microseconds
digitalWrite(trigPin, HIGH); //outputs a voltage of 5V to the trig pin
delayMicroseconds(10);
digitalWrite(trigPin, LOW); //outputs a voltage of 0V to the trig pin
duration = pulseIn(echoPin, HIGH); //Takes in the voltage from the echo pin
//Calculate the distance (in cm) based on the speed of sound.
distance = duration/58.2;
if(distance >= maximumRange || distance <= minimumRange){ //checks the range that is returned from the ultrasound sensor
Serial.println("-1");
digitalWrite(LEDPin, LOW); //turns off the LED
}
else{
Serial.print(distance);
Serial.print(" cm");
Serial.println();
digitalWrite(LEDPin, HIGH); //turns on the LED
}
delay(50);
}

Google's new IOT Developers Kit
from TechCrunch
Android Things, Google IoT platform for developers who want to build connected devices, is now out of beta, as the company today announced. After eight release candidates, the last of which launched less than a month ago, Google now deems Android Things ready for primetime. Despite its beta status, quite a few companies started building products for the platform a while ago, including Google’s launch partners for its Android smart displays, which are based on this platform.
Android Things provides hardware and software developers with all the necessary SDKs to build all kinds of IoT devices. The company has partnered with a number of hardware manufacturers to offer developer kits and also offers a developer console that allows for managing devices and pushing over-the-air updates to both prototype and production devices.
The general idea here is to give hardware manufacturers a managed operating system and certified hardware that free developers from worrying about the system and its maintenance and allows them to focus on building their product. Google promises that it will ship stability fixes and security patches for three years, though manufacturers will have options for extended support, too.

Arduino Kits for Consideration
Four options for your consideration.
The official Arduino kit:
This is the kit provided by Arduino, and it includes the very useful book. AMAZON LINK
Option 1. Minimalist programmer
This is a very inexpensive kit that uses an Uno that is built on the same schematic as the Arduino Uno. It is sold on Amazon by LANDZO and has the minimal basics for programming experiments. Unfortuantely it appears currently unavailable, but is often priced below $9. AMAZON LINK
Option 2. Beginning tinkerer and programmer
Similarly inexpensive is this Elegoo Uno kit, which comes with a small case, a tutorial CD, and a few additional items at just $17.99.
AMAZON LINK
Option 3. Super starter kit
The best value, however, is likely this Elegoo Uno kit with a much greater variety of sensors and actuators, for just $10 more:
AMAZON LINK
Option 4. The comprehensive starter kit
A similarly good value, this kit will keep even avid tinkerers busy for years of learning. It's about double the current price of Option 3, at $59.

Encore Volunteer Needed - May 9
Encore Learning has been invited to participate in a "Retirement Well-Being Fair at George Mason University's Fairfax campus on May 9. The event is intended to help GMU faculty and staff who are anticipating retirement.
The volunteer would staff a table from noon to 1:30 and explain what Encore Learning provides in the way of intellectual and social enrichment. The EL office will provide some collateral materials.
Please email Steve Shapiro at steve.shapiro31@gmail.com (or call 703-622-2760) if you can help out with this event.

Qualcomm Thinkabit Lab and the Workforce
From WorkingNation.com.
Qualcomm Thinkabit Lab is creating the next generation of inventors
By Matt Parke|Apr. 18th, 2018
The ideas which shape our future technology can come from anywhere.
One idea which could help farmers tend their livestock came from the mind of Luis Gomez, with a little help from the Future Ready Lab Inspired by Qualcomm® Thinkabit Lab™ in Porterville, California.
Gomez, 12, is a member of the 4-H Club and he’s got a problem he thinks he can solve. What kind of invention would help him keep his sheep, Lamar, on a regular feeding schedule?
He’s a busy seventh-grader at St. Anne’s School and must dedicate a portion of his day to preparing Lamar for the year-end show and sale. Between school, 4-H and participating on St. Anne’s Academic Decathlon team, it’s a wonder that he has the time for his other hobbies. He’s also a tinkerer who take things apart and rebuilds them and dabbles in video editing too.
Gomez got the spark for his invention after he visited the Porterville Unified School District’s (PUSD) Future Ready Lab, a classroom, makerspace, and engineering lab rolled into one. One day, he may create that invention and change farming forever.
“I know there’s automatic water feeders, but I haven’t seen any automatic feeders. Just regular feeders that can feed your animal when you need it to and take away food when it’s past the time for them to eat so that they learn to eat when they have their food,” Gomez told WorkingNation.
Qualcomm Senior Vice President of Engineering Susie Armstrong said Gomez’s idea exemplifies how the Thinkabit Lab and Qualcomm® World of Work(QWOW™) introduces kids to careers in science, technology, engineering and mathematics (STEM) by inspiring that spark of creativity.
“The Internet of Things (IoT) is a set of devices, like cars and smart cities and such, that are all connected and are all communicating. A great example, a great and real example, of the Internet of Things is Luis’s example of the sheep feeder,” Armstrong said.
Qualcomm is not only developing the world’s wireless infrastructure and the upcoming 5G network; it’s cultivating the next generation of inventors who will use that technology. The Thinkabit Lab shows them a future where they can play a vital role in building the tools which will connect everything.
