I'm currently studying electronics engineering and have been assigned a project based on Arduino IoT. Since we haven't been taught much in this field, I'm looking for Simple yet educational project ideas suitable for a student-level Arduino IoT project. Projects involving sensors, microcontrollers, or cloud integration would be ideal.

There's a Simple fix for that. Just take two half-size breadboards ->snap one power rail from each - > insert the ESP32(one side of pins on breadboard A and the other side on breadboard B)

1. Yes you can. But then you have to turn ON only one LED at a time. 2. It is Simple. If each LED consumes 12mA we get, total current= 12X15 = 180mA, which is below the maximum rating. Now resistor value = 5V/12mA = 416 ohms.
