Week 8 - Continuation of ESP testingz
Introduction: As week 7 was used in preparation for MST, week 7 had no update on telemetry. After attempts on working with the RedBear Blend had been unsuccessful. Mr Joe assigned us to work with an ESP specifically an ESP01. An ESP functions as an Arduino with a wifi module and cost less than $3. However, it has only 2 IO ports and 1 built-in LED. We were tasked to connect an ESP01 with the DHT22 temperature-humidity sensor. The ESP01 would receive the data from the DHT22 connected to an Arduino and display it on a Serial monitor. The previous attempts had been unsuccessful due to firmware issues which resulted in failure even entering AT command mode. This was solved by Mr Joe uploading a firmware inside it but that ESP could only enter AT command very few often. As such, we focused on various other components such as HC-05/HC-06 as well as the Bluno beetle. Up until recently, we started back with new ESP01 that Mr Joe had g...
