As @krambriw said, ESP devices are inexpensive and can do a lot of things.

The ESP32-S2 Mini is very inexpensive and has lots of I/O pins, analog as well as PWM.  
Oh and yes - it is WiFi enabled. Recently I've been programming my devices using MictoPython.

I know many people on the Forum use the Wemos D1 Mini in their projects to collect data and send it to Node-RED via MQTT, so you may be interested in hearing about this device... This is one example (click the purple coloured one) from the WinWin shop on AE.
