Digital flower pot

In one of my previous videos I had presented you with a bright flower pot, but it was with a strip LED RGB and it lacks a bit of precision compared to the type of plant. So I made you another model of flower pot, although it has the same format its peculiarity is that this one is digital, if you need to water 82% moisture in the ground, then it will be shown on the display.

Again, this is an extremely simple project to carry out with an easy-to-do electronics.

Make sure you have the right USB port and choose the Arduino Nano card. Simply install the program in the Arduino Nano and then you will make the adjustments with water when everything is assembled.

If you intend to do your own crimping then cut a wire three strands of 40 cm. Otherwise you can use the wire provided with the EK1940 probe and simply lengthen it.

Once the crimp is complete, insert the connector into place.

Connect the EK1940 probe.

Install the small bar and put two 7mm M3 screws. Do not put the screws directly on the probe because you may damage the capacitor near the screw hole.

Insert the other end of the wire into the top of the flower pot.

Install the case with the probe in the pot.

I like to put a sheath on the wire for a nicer finish, but it’s optional.

Pass the wire into the bottom part of the flower pot.

Fold the wire over itself in case you have to pull the probe out of the ground otherwise the wire will be too short.

Install the wire-cover hood.

Put some glue on the wire below the jar, but it’s optional, it’s just to keep the wire out.

Now we have to stick the Arduino Nano.

If the wire is too long then cut to the desired length.

You’re going to need another piece of four-stranded wire, cut it to 18 cm. Again, I did my crimping, but you can also weld the wires directly onto the pins display.

Connect the connector to the LCD SSD1306 screen unless you’ve already welded the wires directly onto the pines.

Install four 12mm M2 screws with nut.

The screen connector should be positioned downwards.

Click on the image to enlarge the diagram, it’s a very simple connection to make.

Your Arduino parts may not have the same login order, but the Arduino Nano is always the same, be careful.

Connect the USB socket.

See if you see anything on the screen. If the screen doesn’t show you anything then, it may not have been programmed yet.

Once the connections are complete then, close the bottom lid with four 12mm M3 screws, I use wood screws most of the time.


Connect your flower pot to your computer and then put about 7 cm of water in a small glass. Now open Arduino’s IDE software as well as the terminal to see the data on the screen.

Dip the probe into the glass of water.

Change this value as needed.

Remove the probe so that it is in the open air.

Change this value as needed.
