Fluxgrid IoT
Start from a ready-made dashboard. Open one to watch it run on demo data, then copy it into your account — the matching Arduino sketch comes with it. Free to look around; we ask for an account (an emailed code, no password) when you copy one.
Hardware InformationDisplay ESP32-S3 N16R8 details
Home environmentTemperature, humidity and air quality for a room, with a history chart for each. The sketch invents the readings, so you can watch it move before you wire a sensor.
Smart plugSwitch a relay from anywhere and watch the power it draws. The sketch prints the switch to the Serial Monitor and reports a made-up load while it is on.
GreenhouseAir and soil conditions with a pump you can switch on from your phone. Made-up readings first; a real soil probe and relay when you are ready.
Power monitorVoltage, current and the power they add up to, as dials and a history chart. The sketch simulates a small DC load.
RGB lightPick a colour and a brightness from the dashboard. The sketch prints what it receives; wire an LED strip when you want the real thing.
Robot carA joystick to steer, a switch for the lights and a horn button, with speed and battery coming back. The sketch prints your driving and simulates the readings.
GPS trackerA position on a map with the speed and battery of whatever carries it. The sketch walks a made-up position around, so you need no GPS module to see it work.
Device healthWhat your board is: chip, memory, Wi-Fi signal and uptime, straight from the library. Nothing to wire and almost nothing to write.
