Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I found an easy way to test 2.4GHz downconverters for RTL SDR using a nRF24L01 module

Is there anyone out there that can modify this code to add 3 servos?

For this code... How could I edit it so that I could send the readings of a joystick to a second arduino? What is a const char?
/* * Arduino Wireless Communication Tutorial * Example 1 - Transmitter Code * * by Dejan Nedelkovski, www.HowToMechatronics.com * * Library: TMRh20/RF24, https://github.com/tmrh20/RF24/ */ #include #include #include RF24 radio(7, 8); // CE, CSN const byte address[6] = "00001"; void setup() { radio.begin(); radio.openWritingPipe(address); radio.setPALevel(RF24_PA_MIN); radio.stopListening(); } void loop() { const char text[] = "Hello World"; radio.write(&text, sizeof(text)); delay(1000); }

I'm trying to use some nRF24L01 + PA modules but they don't work.
#include //nRF2401 libarary found at https://github.com/tmrh20/RF24/

Arduino-based electronic chess-board I made
The Arduino reads the sensor values and compares them to a threshold in order to create a bitboard (binary representation of the board with each bit representing one square). Whenever the bitboard changes, it's send to the computer via a Serial connection. See serial_binboard.ino.
