ESP 32 Day 5/30 :
(Similar to day 4)
Challenge statement:
Connect your ESP 32 to the internet and send temperature data to the cloud (ThingSpeak) for real time visualization.
Hardware connections were same as day 4. Changes were made in the code.
I made a ThingSpeak account and created a new channel. Then copied the API key in the code and uploaded it to the ESP. The graph generated is shown in the ThingSpeak dashboard.
Also please somebody tell me why it doesn't give the output whenever my WiFi is connected to the laptop and ESP whereas it always works with other's WiFi.
