i assembled the same circuit of dr.acula which is on this link http://drvernacula.topcities.com/lcd_clock_for_controlling_pumps_.htm
and i downloaded the same code but the lcd is just showing squares there's no change when i push the buttons so its not working with me
is this circuit should be done by 1 or 2 hc595 because the schematic is showing only one
