Assignments for week 15:¶

Design and document the system integration for your final project.

1. Overview and working principle.¶

My project consists of two parts, namely CHIRP device with MCU-1 and CLEAN device with MCU-2.So my final project is titles as CHIRP and CLEAN device.

2. Circuit diagram¶

My final project requires the ESP NOW as the protocol for communication between the two XIAO ESP32C-3 PCB.Here is my system diagram that will show communication between my two fabricated PCB.

6.system integration¶

My final project titled CHIRP and CLEAN Device consists of two parts, CHIRP(MCU-1) with DF player mini, speaker, VL53L1X motion sensor and XIAO ESP32-C3.The other CLEAN(MCU-2) consists of DF player mini, speaker, VL53L1X distance sensor, mini water pump and XIAO ESP32 C-3.

The MCU-1(CHIRP) part will act as a master and MCU-2(CLEAN) part as receiver device where they can communicate using the ESP NOW protocol.

While using the ESP NOW to communicate between my two XIAO ESP32 C-3, i need to add the MAC address.I do not need other library for ESP NOW as i have already installed the ESP32 library package by Espressif System. In order to add the MAC ADDRESS, i referred this website and i have used that example code to get my MAC ADDRESS.

You can see more detailed working on this under weekly assignment of Networking and Communication here.

7.Assemblying and testing.¶

7.1 Assemblying CLEAN device(MCU-2) Firstly, i have mounted the mini water pump into its slot of the base.The pump hose and terminals were sent up via the threaded hole of the connector to the top MCU-2 case.
