Observe one low-power SHT45 heater pulse on Pico. Check both CRC words, preserve diagnostic readings and require a stable return near the earlier baseline without inventing ambient humidity.
Build an HX711 and TAL220B scale lab on Pico. Keep tare and span calibration separate, refuse unstable windows and preserve drift instead of automatically zeroing it.
Build a US-100 UART sonar lab on Pico. Refuse stale, partial and missing responses, then explore why target angle and material can change a plausible distance.
Compare edge counts and reciprocal periods with a Pico loopback fixture. Learn counting steps, sampling-gap refusals and why a shared clock cannot calibrate itself.
Derive exact exponential PWM-filter ripple, include the meter as a load, and compare 1 kHz with 10 kHz using a complete Pico trial and ideal calculator.
Read fresh BMP390 pressure with a complete Pico driver. Track a short-lived local reference and show why weather, heating and air models prevent an automatic exact height.
Decode Raspberry Pi4 current and historical health flags separately. Use a read-only Python snapshot that preserves unknown bits, command failures and firmware identity.
Measure PIR output intervals with a Pico while separating startup, H/L retriggering and software qualification—and never turn pulses into a people count.
Generate three MCP4726 voltage steps at3.3 V. Compare DAC node and loaded terminal, calculate reference and resistor effects, and keep bus acknowledgements separate from measurements.
Build a Joy-IT KY-020 and Pico event logger. Separate startup, contact chatter, settled transitions, missed short pulses and sampling gaps with complete MicroPython code.
Explore these do-it-yourself project kits. Check the selected option, included parts and instructions on each offer.
