The Research Control Combinator is a tool for automating research selection in Factorio's Space Age infinite research
Signal-Based Research Control: Send virtual signals to the combinator to set the research automatically.

Instructions:
Build the Research Control Combinator in your factory and connect it to your circuit network.
Send Virtual Signals:

Use the signals listed below to trigger specific research projects. Connect a constant combinator or logic network to control the combinator.
Signal-to-Research Mapping:

Send the following signals to the combinator to select the desired research:
signal-1 Stronger Explosives
signal-2 Refined Flammables
signal-3 Plastic Bar Productivity
