Processing scale aware plotter for Arduino usable as coarse oscilloscope. Two Arduino code examples provided.
// Time Aware Plotter
// License: Creative Commons BY-SA
// This program takes ASCII-encoded strings from the serial port at 9600 baud and graphs them.
// It expects up to 6 comma separated values in the range 0 to 1023 followed by a newline.
// Plotting must be started with a mouse click and can be paused with a mouse click as well.
// Please note: while plotting is stopped serial data is discarded!

ManiacBug's RF24 library example working on Arduino micro connecting the NRF24L01 module on the Arduino micro pins (not the ICSP header) and pins 9 and 10
#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
#include "printf.h"
// Set up nRF24L01 radio on SPI bus plus pins 9 & 10
RF24 radio(9, 10);
// Radio pipe addresses for the 2 nodes to communicate.
const uint64_t pipes[2] = { 0xF0F0F0F0E1LL, 0xF0F0F0F0D2LL };
