The CEC will get you up to speed quickly on a host of technologies you've been meaning to study via a series of 45-minute online lessons taught by our faculty of expert tutors.
September 21 - Day 2 – Sockets and Raspberry Pi 4B GPIO
Now that we have established and verified our Raspberry Pi 4B baseline configuration, we can now put our Raspberry Pi 4B-based IoT platform to work. Today, we will code a TCP/IP socket application that targets the Raspberry Pi 4B’s GPIO subsystem...
August 27 - Day 5 – Simulator Driving and Mobile Robots
Participants will learn to operate their Osoyoo mobile robot with a mobile simulator driving app.  They will assemble a Bluetooth module to the compatible Arduino development board and will learn Bluetooth basics while testing their simulator...
August 26 - Day 4 – Mobile Robots and Ultrasonics
Participants of Day 4 will learn about robots and ultrasonic sensors from the basics through experimentation with a TinkerCAD circuits model. Participants will assemble and test their mobile robot with the assembled ultrasonic sensor.
August 25 - Day 3 – Mobile Robots and Infrared (IR) Control
Participants will learn to operate their mobile robot with IR remote control, the basics of IR detection, and the associated electronics technology. Participants will assemble the IR receiver to test their Osoyoo mobile robot.  Test code for...
August 24 - Day 2 – Mobile Robot Body Platform
Various construction platform methods of building a mobile robot body will be discussed on Day 2. Participants will be instructed on building their Osoyoo mobile robot. Appropriate electrical wiring and circuit schematic diagrams for attaching the...
August 23 - Day 1 – Mobile Robots: An Overview
CEC participants will be introduced to mobile robots. Participants will gain a historical perspective of mobile robots and an overview of the Osoyoo mobile robot kit. A discussion on the main sections of a mobile robot will be presented. A hands...
July 30 - Day 5 – RP2040 PIO Primer
The RP2040’s PIO state machines are unique to the RP2040. Today, we will use CLion to build an instance of the pioasm application, which runs on a personal computer. The pioasm application is used to assemble PIO assembler source code that is used...
July 29 - Day 4 – Coding an RP2040 Weather Node
The RP2040 is not equipped with an on-chip data radio of any kind. So, we will take advantage of our newly enabled UART and use it to add XBee data radio capability to our RP2040 hardware. In today’s lecture we will use the XBee data radio to...
July 28 - Day 3 – Enabling the RP2040 SPI Portal
Once again we will dive into the RP2040 data sheet to craft some code that will enable one of the RP2040’s SPI portals. Today’s ultimate goal is to activate some RP2040 SPI hardware that will drive a TFT display. Again, we will use the Saleae...
