| Recording to OpenLog example | ||

| License: This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license). | ||
| This is an example of basic recording to OpenLog using software serial. This example is best for users who | ||
| want to use OpenLog with an Uno or other platform capable of softwareSerial. | ||
| Connect the following OpenLog to Arduino: | ||
| RXI of OpenLog to pin 5 on Arduino | ||
| VCC to 5V | ||
| GND to GND | ||
| This example records whatever the user OpenLog.prints(). This uses software serial on pin 5 instead | ||
| of hardware serial (TX/RX pins). Nearly any pin can be used for software serial. | ||

| License: This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license). | ||
| This is an example of basic recording to OpenLog using hardware serial. This example is best for users who | ||
| are plugging the OpenLog directly onto the programming connector on an Arduino Pro Mini or Arduino Pro. | ||
| We DON'T recommend this method for beginners. See Example 1 for an easier software serial example. | ||
| The reason is if you upload a sketch to an Arduino with OpenLog attached then OpenLog will log the | ||
| uploading of your sketch. This may cause the OpenLog to become reconfigured. No harm will be | ||
| caused but it can corrupt the log file. | ||
| Connect the following OpenLog to Arduino: | ||
| RXI of OpenLog to TX on Arduino | ||
| VCC to 5V | ||
| GND to GND | ||
| This example records whatever the user Serial.prints(). This is the easiest but NOTE: You cannot | ||
| upload sketches to your Arduino with the OpenLog attached (because of bus contention). Upload this | ||
| sketch first, and then connect the OpenLog to the TX pin on the Arduino. | ||
