1. Engineering Innovation Center
Microcontroller II PopUp Course
2017

2. Introduction to Microcontroller II
The Engineering Innovation Center is a large academic maker space with plenty of tools, electronics and equipment. In order to use these items you must have the proper training. This online popup class will teach the basic fundamentals of this tool or piece of equipment.
Microcontroller II – teaches the basic uses of the Raspberry Pi 3 microcontroller. The key is the right tool for the right job. This class will give basic information on how the Pi 3 works, how to program it, and when to use it.
To complete the certification for the Microcontroller II class you will need to check out a Raspberry Pi 3 from the EIC Equipment office and complete the online quiz.

16. Programming the Raspberry Pi 3
Python is your best friend
Python community will give you great programming tips
Use Python to program the Pi 3 interface!

17. Example #1 using Python to activate the GPIO Pins This code flashes the led on and off.
Simple circuit to activate an LED. Requires:
LED
Breadboard
Jumpers
330ohm resistor
Open IDLE : MENU -> Programming -> IDLE 2
File - New - Write Script ( Optional: Save to Desktop)
Debug - Run Module

18. Raspberry Pi 3 Example #2 – Blynk App
Get the BLYNK AP for your tablet, phone.
The BLYNK app allows you to assign visual widgets to control devices. BLYNK is a wifi device.

19. Setting up the BLYNK APP
Blynk consists of three components: the app, the server, and the library. The library runs on the Raspberry Pi (or on any supported board) and does all the behind-the-scene jobs of interfacing with the hardware. The app is the core component of the Blynk platform, and it provides an environment for building visual interfaces for controlling Raspberry Pi. The app offers a collection of widgets, such as button, sliders, LEDs, value displays, and the like. To create a graphical interface using the app, you simply add the desired widgets to a project and configure their settings.
The server component provides a link between the app and the Raspberry Pi running the library. By default, the platform uses the cloud service provided by the Blynk project. The server is released under an open source license, however, and you can easily deploy it on your own machine. In fact, you can even run both the server and the library on the same Raspberry Pi, although it might be prudent to use a dedicated machine or a virtual private server for that.
To get started with BLYNK, you need to install the required components. First, install the mobile app on your Android or iOS device from Google Play Store or Apple App Store. Next, you need to deploy the Blynk library on the Raspberry Pi.
To set your Pi 3 up to run correctly by visiting this website and following the step by step directions. Raspberry Pi GEEK. Go here for more info on the BLYNK app.

20. Setting up the BLYNK APP - Part 2
