Greetings

Hi,

This blog will entail the journey of a capstone project done at George Brown College under the fictional company GBC Ink.

Thanks,
Michael

Capstone Update February 22, 2019

Hi, We have ditched the idea of taking information straight from the BACnet client and putting it through Node-Red and into cloud, instead we can explore a different option, MQTT. MQTT (Message Queuing Telemetry Transport) protocol is an open source protocol which can be run on the Raspberry Pi 3 and Node-Red. This protocol is mostly used for sensor networks where there is a massive amount of data being transferred to a single point. To make a connection to MQTT we can either use another Raspberry Pi 3, NodeMCU Esp8266 or Arduino Wifi. Arduino Wifi is the oldest out of all of them and Raspberry Pi 3 seems like overkill, so we will explore the NodeMCU Esp8266. The NodeMCU Esp8266 has WiFi capabilities and therefore can connect with MQTT. We will be programming it through Arduino, for a quick start guide on how to set it up for Arduino please visit  here . Assuming everything is set up, we need to install the WiFi and pubsub libraries which can be done by going tools, manag...

Capstone Update February 1, 2019

Greetings, This week our team helped other teams with their capstone projects. The one we were working on was the Condominium lights with the green button, we tried to use this button to control the lights through an ESP8266 programmed to toggle, but we were having issues with flickering we eventually figured out the reason why and we are going to fix it next week. Button layout, it is a Form C The ESP8266 we are using is from NodeMCU. It operates at 4.5V-10v usb powered. It has WiFi and IO capabilities. ESP8266 from NodeMCU By utilizing a toggle code, we can effectively toggle the lights without a toggle button allowing us to press the button once to turn on all relays for the lights and again to turn off all relays for the lights. The LED lights were working with are 36 VDC. The code we used to toggle relays Initially the group that was working on the lights programmed the toggle wrong, so we had to fix up their code. Once the code was working more issues popped up...
