Connect the exact three-volt MLX90614 to Pico, verify PEC and error flags, and investigate why target size, distance, emissivity and package temperature affect an apparent reading.
Read raw SGP40 gas counts on Pico with CRC, self-test and a controlled cadence. Keep compensation assumptions, conditioning and unimplemented concentration/index outputs explicit.
Read an exact AS5600 module with Pico, qualify magnet status and cross the zero boundary. Learn why gaps and unseen turns invalidate an accumulated angle.
Build a twelve-stage divider, predict slow LED outputs and see why a ripple counter can show intermediate words. Includes a complete Pico adapter and event-order model.
Build a write-only SPI attenuator and measure how wiper resistance, finite endpoints and load change the voltage. Includes complete code and a clear command-only status.
Build a four-bit magnitude comparator with correct cascade inputs. Test bit significance, equality and unsigned ordering with three separate LED outputs.
Build a defined 25kHz fan command through a 5 V buffer. Keep motor power separate, release the output on cleanup and distinguish commanded duty from measured RPM.
Use an advisory local lock before claiming a Pi LED. Test two-process exclusion, normal cleanup, forced death and why deleting a lock file can break ownership.
Build a low-current two-digit display and test blank-before-change scanning, coherent number updates and a late-loop stop without borrowing a large pulse-current rating.
Run a cancellable five-second light beside a heartbeat. Explore modular deadlines, settled presses, missed-edge coalescing and an explicit late-loop stop.
Explore these do-it-yourself project kits. Check the selected option, included parts and instructions on each offer.
