Wifi-control for a 5050 LED strip with ESP32

The 5050-type LED strips are pretty cheap, and can (sometimes) be controlled by ESP32’s fairly easily. The rough idea is to connect the individual color pins to a NPN transistor and to control them with an ESP32 PWM output pin. 5050 LED strips are always set to the same color, you can’t control them individually. There are different voltages of strips available - we’re using 5V since they seem to be pretty cheap, and they can just be powered by a USB cable.
