On a previous post, I used the nrf24l01+ wireless chip to communicate between the Raspberry Pi and an Arduino, but only got lights to turn on.
I remember being confused as to why servos would not work, and somewhat left it there.
I started messing around with it again, and I am concluding that it might have been just a power issue.
Here is the servo moving properly:
The Arduino is on the ground due to the short length of the wires powering them.
Just as a recap, what is happening is:
- a C++ program using the RF24 library is compiled in the Raspberry Pi (connected to an nrf24l01+ chip) to broadcast a message. When executed, it will broadcast the message.
- the Arduino (connected to another nrf24l01+ chip) programmed to receive messages receives the message, and upon receipt sends a signal to an Arduino that is wired to the servo to move the servo.
Two separate Arduinos are used, as it seems that the servo library and the RF24 library do not seem to run properly together.
Anways, this finally opens up the potential of having a single Raspberry Pi control various devices in separate locations.
With these nrf24l01+ chips being as cheap as ~$2 a piece, (and ~$5 for an Arduino Pro Mini), it definitely sounds like a cheap way to automate various things around the house.
I might move out of my current apartment in a couple of weeks; maybe I'll start having the Raspberry Pi control more things around the house.
