G+_Ralph Mills Posted September 26, 2016 Share Posted September 26, 2016 Originally shared by Ralph Mills Adventures in Arduino continued: Sorry for the poor picture. Just showing the Nano attached to a $2 USD 1602 LCD mounted on perfboard with a 10Kohm contrast pot and a 220 ohm backlight resistor. Display reads "73 de AB1OP" and the seconds since last reset. I have a second 1602 LCD I want to attach to an I2C serial display adapter to be able to reclaim four of the Digital I/O pins used in this arrangement.
