Arduino Sensor Processor

Need an Arduino Nano programmed to receive both analog and digital signals from various transducers and set output pins to high or low according to prescribed logic. The Arduino will also send signals back and forth via an I2C to another microcontroller. I already have the block-diagram and pseudo code written for this program. If you have experience with Arduino programming and transducers such as temperature and humidity, and if you have experience with I2C bus data transfer, please reach out to me.
