Attach SEEED relay shield v2.1; Load Arduino Uno with include ino; Attach BMP180 sensor to Arduino (3.3V to VCC, GND to GND, SCL to A5, SDA to A4) Connect basic button to GND and D2 and LED to GND and ...

Now open Relay.ino and send it to your arduino. it will now start. It is now possible to disconnect from your computer. you can connect the usb or the power to anything else as the arduino remembers.

Users can then add a relay that can be easily turned on or off through a port on the arduino. They can also add Bluetooth or wi-fi connections, and then program more complicated functions.

Simply connect the moisture sensor and the water pump (through the relay) to the Nano RP2040 Connect board, insert the moisture sensor in a flower pot, and put the pump in a recipient filled with ...
