In previous lesson, we've learned how to output Raspberry Pi data through IIC (sometimes call I2C) and display characters in 1602 LCD . This lesson, we'll  combine our knowledge learnt from Lesson 11 and Lesson 13. We will use a potentionmeter to change voltage, convert the voltage analog signal to digit signal through MCP3008 and send it to Pi via SPI. Then Pi will send  voltage data via I2C and display data on 1602 LCD screen.
