Have you wondered how information from physical devices in the real world gets communicated to Smartphone processors? Do you want to make informed design decisions about sampling frequencies and bit-width requirements for various kinds of sensors? Do you want to gain expertise to affect the real world with actuators such as stepper motors, LEDs and generate notifications? In this course, you will learn to interface common sensors and actuators to the DragonBoard™ 410c hardware. You will then develop software to acquire sensory data, process the data and actuate stepper motors, LEDs, etc. for use in mobile-enabled products. Along the way, you’ll learn to apply both analog-to-digital and digital-to-analog conversion concepts. Learning Goals: After completing this course, you will be able to: 1. Estimate sampling frequency and bit-width required for different sensors. 2. Program GPIOs (general purpose input/output pins) to enable communication between the DragonBoard 410c and common sensors. 3. Write data acquisition code for sensors such as passive and active infrared (IR) sensors, microphones, cameras, GPS, accelerometers, ultrasonic sensors, etc. 4. Write applications that process sensor data and take specific actions, such as stepper motors, LED matrices for digital signage and gaming, etc....

The students who taught this course did an amazing job of putting together the lectures and code.

Really interesting section of the specialization, where you learn how to connect your device to the outside world. Plenty of ways and interesting examples. The coding part sometimes is difficult to follow, but as code is available and documented, you can still grasp how it works.

Good hands on course. The self built amplifier circuit feels like a hack but works around the voltage level issues adequately without the mezzanine board which was not available at the time the course was prepared.

Headed downhill. Lessons are starting to feel like not enough time was put into preperation... or like this course was assigned as a project to some students so the professor could make a dollar (like textbooks). One of the instructors even said at one point they didn't have enough time. What does that even mean in an online course. You could be fixing it right now and improving the course. This whole thing is being handled like a college course and that is crazy. On-line courses can undergo continual improvement. The college course paradigm is dying because we can do it better now. Fail.

Way too basic. Probably only suitable for absolute beginners.
