ESP8266 with Temperature Sensor
I bought my first Arduino board a couple of years ago. It didn’t take long before I wanted to have some kind of network capability for my board so I bought some ESP8266 01 WiFi modules afterwards. Then I learned that ESP8266s are actually powerful enough to run simple codes. I have an obsession with overhead in my personal projects so I realized that I did not need the Arduino anymore and could ditch it.
