Projects

Ideas to start from, drawn from documented sources. Or answer three questions for a personal shortlist.

• Log temperature over Wi-Fi

  Reading a temperature (and humidity and pressure) sensor such as the Bosch BME280 over I2C from a Wi-Fi-capable board, and sending readings over Wi-Fi. Documented Wi-Fi options include ESP32-DevKitC and Arduino UNO R4 WiFi; the receiving logger is not covered.

• Read an analog sensor with a Raspberry Pi

  Reading an analog voltage from a sensor on a Raspberry Pi 5 using an external I2C analog-to-digital converter (ADS1115) on the 40-pin header's I2C pins, with Python on Raspberry Pi OS. The documents read list no analog input on the Pi 5 header.

• Compare boards: documented capabilities

  A side-by-side of what Arduino UNO R3, UNO R4 WiFi, ESP32-DevKitC, Raspberry Pi 5, Pico, Pico 2 and Zero 2 W are documented to be and offer: what each is, how it is programmed, wireless, and GPIO logic level. Price is not compared.
