- '''Signaling rules:'''
+===[[1602 LCD using I2C Adapter]]===
- * Inactive bus - no communication: Both SCL and SDA are high
+==The Old Website==
- * For normal data flow, the SCL must be low when the SDA signal changes.
+http://www.merkles.com/original_index.html<br>
- * Start Condition: With SCL high, the SDA signal is pulled low.  This condition
+<br>
-   wakes all the I2C devices on the bus, alerting them to begin watching for their address.
+'''Questions?  Suggestions?  Contact me: jim@merkles.com'''
- * Stop Condition: With the SCL high, the SDA signal is raised from low to high.
-   This condition signals all the devices on the bus that communication is complete with the
-   current device, and the bus should return to an idle state.
- * Any of the devices connected to this bus has the ability to pull its associated I2C bus signal low.
-   The pull-up resistor will pull the signals to a high state when none of the I2C devices are pullin
-   the signal low.  When both the "SCL" and "SDA" signal are both at stable high level, the bus is
-   considered "inactive" or available (usually following a Stop condition).

-== Blinky ==
-Blinky is often the first program used to begin learning the Arduio environment and to test the development board to verify a program can be written, compiled, downloaded, and executed.  Blinky is available in the Arduio menu under {{Highlight |File->Examples->01.Basics->Blink}}.<br>
-<strong>Key APIs (functions)</strong><br>
-* pinMode(LED_BUILTIN, OUTPUT);
-* digitalWrite(LED_BUILTIN, HIGH);
-* delay(1000);<br>
-== ASCIITable ==
-ASCIITable is rather boring, but provides an example of how to use the Arduino's serial port to send messages to the console window (or to any serial terminal program.)  Since the Arduino platform doesn't provide a debugger, it's often required to add serial print statements into your program to see how the program is progressing, and to see what the values of certain variables might be.  ASCIITable is available in the Arduio menu under {{Highlight |File->Examples->04.Communication->ASCIITable}}.<br>
-<strong>Key APIs (functions)</strong><br>
-* Serial.begin(9600);  // Use 9600 for the serial port data rate (9600 and 115200 are very common values)  Be sure to tell your Arduio console window the data rate (baud) you selected here.
-* Serial.print("Fred");  // Display the text, "Fred"
-* Serial.println("Some text to display");  // Display the text, "Some text to display", and begin a new line below it
-* Serial.write(thisByte);  // Display the ASCII representation of the byte, "thisByte"<br>
