A deliberately modest DRV8833 module separates PWM commands, winding-current trip and motor motion. Full Pico code includes coast reversal delay and a latched fault path.
Play an original synthesized Jingle Bells MP3 through a DFPlayer Mini and speaker, with a Pico-controlled six-LED animation. Includes schematics, code and prototype limits.
Trace an SPH0645 microphone’s power and I2S format, decode signed samples, and compare peak, RMS and known digital clipping without claiming acoustic calibration.
Feed measured BMP390 pressure into SCD41, verify100Pa command units and readback, and reject stale updates without confusing compensation with CO₂ calibration.
Weigh a pot and its drainage collector on independent HX711 platforms. Use separate calibration and observed read windows to distinguish compatible transfer from unknown loss.
Combine room humidity and a contacted window temperature, then calculate a conditional margin interval that keeps uncertainty and acquisition timing visible.
Separate signed liquid flow from air and saturation flags, then calculate a conditional subtotal only across usable SLF3S-1300F read intervals.
Delay a Pico capture consumer and compare blocking with nonblocking PUSH. Learn why contiguous tokens and a quiet FIFO cannot prove a complete event history.
Read an SPS30 with a Pico, preserve the gap during fan cleaning, and reject CRC, status or stale-data failures without presenting cached values as new.
Compare two water-probe polarities with a finite Pico capture, retain raw ADC readings, and calculate a signed late-window proxy without claiming total charge.
Explore these do-it-yourself project kits. Check the selected option, included parts and instructions on each offer.
