Firmware (Arduino Sketch) file for the Arduino-based Digital Inductance & Capacitance Meter [Arduino_LC_meter_sketch.HEX]
.ino sketch for the 8-bit Arduino microcontroller in the Arduino-based Digital Inductance/Capacitance Meter.
Now updated so it includes the required libraries (zipped).
Please note: you may need to change the LCD address in the third non-comment line of the .ino file before uploading, depending on whether your I2C module has a PFC8574T (0x27) or PFC8574AT (0x3F). The sketch by default is set up for a PFC8574T. See the comment at the top of the sketch and the article in the March 2017 issue (El Cheapo Modules Part 5).
Version 1.2 now includes the updated LiquidCrystal_I2C library which should solve compilation issues.
Version 1.3 includes a bugfix to the LiquidCrystal_I2C library which allows it to work with the latest version of the Arduino IDE.
