==== I²C scanner ====
{{:de:project_s7:uk.png?16|english}} This sketch tests the standard I²C 7-bit addresses. Devices with higher bit address might not be seen properly.

// --------------------------------------
// i2c_scanner
//
// Version 1
// This program (or code that looks like it)
// can be found in many places.
// For example on the Arduino.cc forum.
// The original author is not known.
// Version 2, Juni 2012, Using Arduino 1.0.1
// Adapted to be as simple as possible by Arduino.cc user Krodal
// Version 3, Feb 26 2013
// V3 by louarnold
// Version 4, March 3, 2013, Using Arduino 1.0.3
// by Arduino.cc user Krodal.
// Changes by louarnold removed.
// Scanning addresses changed from 0...127 to 1...119,
// according to the i2c scanner by Nick Gammon
// http://www.gammon.com.au/forum/?id=10896
// Version 5, March 28, 2013
// As version 4, but address scans now to 127.
// A sensor seems to use address 120.
//
//
// This sketch tests the standard 7-bit addresses
// Devices with higher bit address might not be seen properly.

===== SIM900 Tools =====
==== SIM900 serielle Kommunikation ====
{{:de:project_s7:de.png?16|deutsch}} Kommunikationsprogramm zum Testen des SIM900-Moduls. Befehle müssen in der Befehlszeile des seriellen Monitors (mit ENTER) ausgegeben werden. Der Monitor muss auf //"auch NL als auch CR"// eingestellt sein.
Weitere Informationen zum SIM900 finden Sie hier: [[de:arduino:gprs#at_coms|SIM900 quad band GSM-GPRS shield]] \\
