This article extends the node tree of ProjectDiva to include an Arduino Pro Mini.
This article explains how to connect a Arduino Pro Mini to the nRF24Things application (Android Things). The code allows sending and receiving messages between the nodes. It uses the well-known nRF24 libraries to create a sensor mesh, where the node 0 (in this case a Raspberry Pi running the Android Things application) actuates as a "DHCP" server and assigns the node addresses in the mesh.

I've recently updated the
nRF24Thingsproject. I introduced some changes to the database main table (
sensors) and to the handler class
DatabaseHandler. Additionally, I added a second table for the payloads (
payload). The two tables are related using the foreign key
nodeID. I added some search options for the payloads: search by payloadID, nodeID etc.
The main idea of this project is to measure the humidity, temperature, air quality etc. of a room with multiple sensors (may be using the Pi...

I had some humidity problems in the basement and I thought I can buy a dehumidifier. I bought this one on banggood Dehumidifier 500ml. I knew they are not good enough, but I wanted to try.
This type of dehumidifier uses a peltier element to cool an alumium disipator (peltier cool side), which condenses the humidity. The condensed humidity drips into a water tank until it is full. Then, a switch is triggered and the system stops. The peltier hot side has a bigger disipator and together with a fan disipate the generated heat.

I've recently updated the code for the communication between the raspberry pi v3 and the rf24l01+ module using android things (0.)4.1.
You need the following things:

I've just uploaded the Java codes for the
rf24Meshthat work with Android Things. This time I didn't write a library because I thought it was better to upload an Android project that can be opened with Android Studio (>2.2.3) and directly started on the Raspberry Pi. I think this can also work with NXP Pico i.MX6UL and Intel® Edison with minor modifications (especially in the
