The IoT Curriculum Map
A gateway means a bridge between systems that use different links or rules.
Start with the thing you want to build, then choose the smallest learning path that explains it. A home sensor, a farm gateway, and a secure factory monitor all use different parts of IoT, but each one can be traced through the same promise: sense something, move the data, make a decision, and prove the system is safe enough to trust.
Use this page like a map rather than a catalogue. Pick the card that matches the next evidence question in front of you. When that question is answered, come back and take the next small step.
