MeM Modular emergency Mesh

The final project parts:

Alert light system - Modular emergency Mesh

The entire project has many parts to be manufactured all, so I had to buy parts, others are borrowed and some had them before. This lighting system is considered an important part of the final project because it puts the domain of circuit design evident, the embedded programming and PCB fabrocación. This device connects to the network via an ESP8266 connected to an Atmega 328. The design process was an iteration from the breadboard with Atmega 328 through-hole soldering. Here you can download all the board files, eagle, .png and .rml. The codes are here

1. Electronic Design

2. Electronics Production

3. Embedded Programing

I started welding the Atmega 328 ISP connector, an LED connected to power and one connected to a digital output. In this way, I can test with minimal components if the board and the integrated function properly, so you can continue welding the other parts. I test the programing with Arduino IDE. I started by using blink sketch. For this attempt I used the internal clock

Once assembled all the components of the logical part, a test of the serial communication is made. In this step, I realize that the TX to RX in the schematic are changed, so I corrected with pin cables and tried the serial communication program used in this assignment.

Description:

My final project is an Emergency modular wifi mesh network. The idea is to setup a node that can use the mesh network protocol, this results in a modular network that grows as more nodes are added. This node is capable of providing internet or intranet fo large areas (depends on the numbers of nodes), also can get real-time data from the territory, cause it publishes sensor data trough web platform. This platform can help to reveal the state of a catastrophe cause the users could alert authorities and others neighbors even if the power and internet are down, cause it is completely autonomous, it have its own web server, solar energy, and other sensors and actuators like lights alerts. When the nodes can`t connect to the internet it works as intranet, that means users can connect each other and share data on real time.
