Arduino Blink Challenge
Emerging engineers read about Arduino software and how it can be used. Then they follow a nine-step tutorial to connect an Arduino board to a computer and put it to work! The objective is to code a program that will cause an LED to...
Teach Engineering
Life Cycles
Breathe some life into product design. Pupils learn about the stages of product creation, use, and disposal—sometimes called a cradle-to-grave assessment. They see how this cycle relates to the life cycle of organisms.
