Bright flower pot

This week, I have to present a project that is very simple to carry out, but very practical. You will no longer lose your plants because they have run out of water, a simple glance is enough to make you think of watering your plant. The base of the pot has four different colors, green, blue, orange and red.



File to download:

You’re going to have to change these settings using The Arduino software.

This part is a bit complicated, you need a glass of water and also, you have to open the Arduino software terminal. Dip the probe in 5 cm of water and wait about a minute then open the Arduino terminal, you will see a number followed by the percentage, replace the number at the end of “map_high ” by the number you have on your screen.

Same as the previous step except that you will remove the probe from the water and that you will replace the number of “map_low ” instead.

You can also change the colors of the LEDs.

Assembling the dryer

Screw the TE215 probe onto the inside lid.

Pass the wire through the top hole and then install a connector to connect to the TE215 probe, if you don’t have a connector, then weld the wires onto the probe.

Once the wire is connected (or welded), the lid remains to be inserted inside the pot so that the probe touches the ground. This can be done before or after the earth is in the pot. Make sure you have enough wire for a possible sensor replacement.

It should look like this once installed.

Insert the other part of the wire into the bottom of the pot.

Install the lid back.

Put glue on the two rails below the pot.

Install the Arduino Nano on the glue.

Glue the underside of the sensor controller and paste it where you want.

Connect the probe to its controller (see diagram, you’ll see the FC-28 probe).

Weld the probe’s A0 wire on the Arduino Nano terminal A0, then the controller’s VCC on 3V3 of the Adruino Nano, then the GND on the GND of the Arduino Nano.

Install the LED strip.

Weld the wires of the LED strip on the Arduino Nano, the () on THE Vin of the Arduino, the (-) on GND and the other wire on D5.

Install the cover below and then the assembly is complete.


I hope you enjoyed this project, I know it’s nothing complicated, but I also know that it will be very convenient for everyone.

Green: The soil is quite wet, so no need to water.

Blue: the soil is not very wet, it is not necessary to water, but the plant would like to have some water.

Orange: You need to water your plant.

Red: Humm… Not sure the plant will survive unless it’s a cactus.
