    I need a simple UIFlow program written based on the M5 Stamp Pico to receive thermal sensor readings from an M5 NCIR 2 (I2C). The readings are displayed on a M5 1.14" I2C Color LCD (ST7789V2) where active temp text is displayed over a static background image. The program establishes a temperature variable above which a (fan) control signal activates an M5 3A Relay Unit. Grove connectors are used throughout, except for power leads to the Stamp Pico. A M5 2 Unit can be used to manage I2C components if required. All M5 components have been sourced from m5stack.com. This program code is needed to utilize the referenced components for monitoring the temperature of a sensitive transistor in radio application. Skills Needed: - Knowledge of ESP32 microcontroller M5 Stamp Pico. - Experience ...
