Turn a DS18B20 CSV log into a local Raspberry Pi dashboard. Show fresh, stale, missing and invalid readings separately with a small Python server.
Compare raw, mean and median readings from a Pico potentiometer. Inject labeled software spikes and measure the smoothing-versus-response tradeoff.
Connect two Pico boards with a one-way UART link. Send framed readings with CRC-16, reject damaged messages and show when data stops arriving.
Decode a mechanical rotary encoder with Pico using a quadrature transition table. Count complete cycles, reject impossible jumps and expose missed edges.
Read a 10 kΩ NTC thermistor with Pico. Derive resistance from a divider, estimate temperature and recognize open-circuit and short-circuit readings.
Use a Pico analog input and three resistors to distinguish a closed contact, open contact, short and disconnected cable. Includes fault-injection tests.
Record room temperature with Raspberry Pi and a DS18B20. Includes 3.3 V wiring, Linux 1-Wire setup and Python CSV logging with error handling.
Turn distance into sound with a Raspberry Pi Pico and HC-SR04. Build the echo divider and explore pulse timing and PWM with full MicroPython code.
Overview The Raspberry Pi Pico W, while not having native Bluetooth hardware, opens the door to BLE functionality when paired with additional hardware like an …
