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.
Measure a joystick’s real center and travel. Wire a Joy-IT KY-023 to Pico at 3.3 V, add a dead zone and count clean button presses with complete Python code.
Explore a Pico analog multiplexer with a controlled low-voltage step, compare source resistance and dwell, and preserve channel identity and stale-reading status.
Build a Pico SN74HC595 panel that holds its old pattern while new bits shift in. Compare latch errors, shift clear and output blanking with complete code.
Build a diode-free Pico button matrix, trace a three-key ghost path, and reject ambiguous frames with complete scanning and debounce code.
Build a Pico watchdog experiment that feeds only after fresh acquisitions, catches a stalled task and enters a visible maintenance hold after reset.
Build an LM393B light switch with two calculated thresholds. Include pull-up and LED loading, check input limits and demonstrate hysteresis with known resistors.
Build a low-current 3.3 V MCP1700 battery supply. Measure regulation and dropout with known loads, check capacitor requirements and calculate heat.
Read two DS18B20 sensors on one Pico pin. Keep physical channel names tied to ROM IDs and report missing sensors, CRC errors and reset ambiguity.
Build a Raspberry Pi SQLite log that keeps the latest readings, separates sensor errors from zero and rolls back interrupted transactions.
Explore these do-it-yourself project kits. Check the selected option, included parts and instructions on each offer.
