week 1

This week the group had four meetings (one with a supervisor) to discuss the beginning stages and basic ideas for the project. Our initial plan was to make a satellite tracker using LED matrix to track the satellites passing over the England (and Ireland) but we encountered a problem as the RGB LED Matrix we had was too complex for  the drivers we ordered. So we consulted with our supervisor and decided to change the project to an LED Tweet Mapper. The aim of this project is to allow users search up a keyword, for example football, on a keyboard or hashtag and the LED Tweet Mapper will find any tweets with said keyword on twitter and show on the map where these tweets were made.

Below is a sketch of the basic circuit diagram:


We also decided upon our roles during one of our meetings this week which are:
Project manager - Skye
Designer - Charley
Implementer - Aaron
Technical writer - Ayanfe  

Some limitations to this project may be: 

1. How many LEDs can be powered at once due to current output 
2. Resolution of Map 
3. Location of tweet (will the the location displayed on the map be specific or general?)
4. Having two strips of LED's with one Arduino 

An order for an 8x2 (12x6cm) LED display and a MAX7219 driver was put out to be delivered next week.
 
Next weeks proposed plans:
1. begin plan for lab script
2. power LED and program it with specific colours 
3.  Work with twitter API, and get the code working and ready to interface with the LED's 
4.Develop and co-ordinate the system, with. a 'catchment' for each LED based off the longitude and latitude.

week 4

  This is the last week dedicated to working on the project properly,  as next week is the bench inspection week where supervisors will look at our project, poster, blog etc.  This week the usual group meetings were met and as usual good progress was made. this weeks notes and progress: 1. the casing prototype was printed and delivered. An image of the prototype is shown below: 2. the wifi module for the Arduino arrived but it doesn't work with any software 3. the wrong pcb was delivered, it has the right chip but wrong pcb, so a new one has been ordered.  4. The  random number generator works to find each display depending on the output, there was an issue. with lighting the number the LED correlates to within each display but this has been sorted out now. An issue getting the ESP where codes can be compiled but cannot be uploaded was encountered.  We realised that using an Arduino and separate WiF module was quite difficult to program. This combined with ...
