UART, SPI, and I2C Explained for Beginners

If you're learning Embedded Systems, you've likely heard of UART, SPI, and I2C. These are the most commonly used communication protocols that allow microcontrollers to communicate with sensors, displays, memory devices, and other peripherals.

UART

✔ Simple serial communication ✔ Uses TX and RX lines ✔ Commonly used with GPS, Bluetooth, and GSM modules

SPI

✔ High-speed communication ✔ Uses MOSI, MISO, SCLK, and CS lines ✔ Ideal for displays, SD cards, and memory devices

I2C

✔ Requires only two wires (SDA & SCL) ✔ Supports multiple devices on the same bus ✔ Widely used for sensors and RTC modules

Why Should Students Learn These Protocols?

Understanding UART, SPI, and I2C is essential for anyone pursuing a career in Embedded Systems, IoT, Robotics, or Automotive Electronics. These protocols are frequently used in real-world projects and are common interview topics for embedded engineering roles.

Master these communication protocols, build hands-on projects, and take a strong step toward becoming a successful Embedded Engineer.

Ladyada's desk gets a scope cart

We've always wanted a portable scope cart

for our workspace to have our test equipment either by the desk for firmware work or at the soldering worktable for rework debugging. At our new office, we finally have space for one! We picked up this 'dental cart'

- It is not super fancy, but it is metal, and it came together fairly easily. We like the mini top shelf for the scope and the second shelf underneath for the power supply and electronic load. The drawer can hold leads or probes. We've locked it next to our desk so we have more desktop space, and it's easy to peek over as we bring up new boards like the metro RP2350

Coming soon! Sign up to be notified when these are in stock and shipping. We'll be updating this to use the 80-pin version of the RP2350

We'll also get the VGA output into our video streaming setup to show off signals we're working on.

Desk of Ladyada - Sparkle Motion Tester Troubles & Samples Sunday 🤖🧠✨🦖📦

Sparkle Motion Mini testers. The Mini came together fast, but classic testers had cascading issues. We used Claude for firmware and got cool samples, including filament letters and enclosures for Sparkle Motion Stick. And our dinosaur tissue holder fell, disassembling an arm! Time to find strong foam tape for reattachment.

Multi-layer electronics development is a structured process that includes requirement analysis, schematic design, stack-up planning, PCB layout, simulation, manufacturability checks, fabrication, assembly, firmware integration, and final testing to ensure high-performance and reliable electronic systems ready for production.

PCB programming and debugging help engineers verify that electronic boards communicate correctly with sensors, processors, and connected devices. By testing firmware, checking signal flow, and identifying software or hardware issues early, engineers improve system stability, reduce failures, and ensure reliable PCB performance in real-world applications.

Embedded systems are tested by checking both the hardware and firmware together to ensure the device works correctly in real-world conditions; engineers perform tests such as functional testing, signal validation, power analysis, communication checks, sensor calibration, and stress testing using tools like oscilloscopes, debuggers, and monitoring software—during the process, they identify issues like unstable voltage, firmware bugs, overheating, or communication failures before deployment; proper embedded system testing improves reliability, safety, performance, and long-term stability across connected electronic devices.
