Arduino + Digital Read Out = arDROvino
Recently I have retro-fitted my sliding table saw with a digital readout , but unsatisfied from the minimalist default display, i have re-designed the display unit using Arduino + lcd and button unit.
Scale clk and data pins are connected to pin 8 & 9; clk pin from arduino is lowered to 3.3 volt logic by a simple resistor network. See source code for details.
Many thanks to Yuriy and all the others who share their knowledge on the internet.
