About the lowest cost platform is the PSoC4 Prototyping Kit (CY8CKIT-049 42xx) from Cypress Semiconductor (about $4) and the development software is completely free and unrestricted. (PSOC Creator). This module is significantly more powerful than a low cost arduino, however this and most other low cost platforms doesn't include a full internet connection, it only has a USB interface which would need to connect to another computer that is on the internet if you want a complete IoT system.
To get started Element14 ran a great series called 100 projects in 100 days - all on PSoC4 applications. They used the Pioneer Kit, but can all be adapted to the Prototyping Kit which uses the same MCU.
