IoT PlaygroundLearn how smart devices think, by playing
Pick a game. Each one has real sensors to watch, devices to switch and simple rule cards that make things automatic. No electronics experience needed.
FLOATech Pond Simulator
Keep a tilapia pond healthy with oxygen, temperature and pH sensors, a solar-powered aerator and an automatic feeder.
Play · 5 missionsKeep the Plant Alive
A soil-moisture sensor, a little pump and a grow light. Keep a plant happy for a week. The easiest place to start.
Play · 4 missionsMy Korean Room Monitor
Temperature, humidity, fine dust (미세먼지) and CO2 in a small studio room in winter. Make the floor heating, humidifier, air purifier and window smart.
Play · 5 missionsSensor Detective
Ten mystery cases from ponds, gardens and rooms: read the sensor graphs and work out what went wrong.
Play · 10 casesCircuit Playground
Wire LEDs, a button, a light sensor, a temperature sensor and a buzzer to a board, and watch your first circuits work.
Play · 5 challengesFrom student design projects
Six games based on engineering design projects by Computer Engineering students at Holy Cross of Davao College. They are proposed designs; each game simulates how its system is meant to work, and its Learn tab says which numbers come from the design and which are game values from published sources.
Tuba Master
Turn sweet coconut sap into coconut wine (tuba) and harvest it before it turns sour.
Play · 5 missionsCopra Power
Burn coconut shells to dry copra and charge a battery, and keep the smoke safe.
Play · 5 missionsUV Tomato Guard
Keep market tomatoes fresh with gas sensors and a safe, lid-locked UV-C cycle.
Play · 5 missionsSeedling Chamber
Vent the heat, water by soil moisture and keep the damp away so tomato seeds sprout and grow.
Play · 5 missionsCold Cart
Keep a market vendor's fish cold all day with a solar Peltier cold box, and don't let the hot side overheat.
Play · 5 missionsCurb-E Smart Sign Patrol
Run a solar AI sign that catches parked cars without flagging drivers who only stopped briefly.
Play · 5 missions1. Watch the sensors
Gauges show what each sensor measures right now, with the healthy range in green. Tap one to learn what it means.
2. Write rule cards
"IF oxygen is below 4 THEN aerator ON." Simple rules like these are how real controllers decide what to do.
3. See the real code
Every game turns your rules into Arduino code, so you can see how they would run on a real microcontroller.
Made by Johnstheward S. Alvarado. The simulations are simplified to run in a browser, but their healthy ranges follow published sources, listed in each game's Learn tab. Your stars are saved only on this device. Sound starts when you first tap a game, including rain, wind and birds that follow the weather; the speaker button turns effects and music on or off.
