Writing stuff to the LCD display with an Arduino
Aus DL8RDS Wiki
Yes, and this made me curious if I can also print the digitized value of the poti voltage to my LCD screen. I modified the program a little:
#include <LiquidCrystal.h> int potiPin = 0; LiquidCrystal lcd(12,11,10,9,8,7,6,5,4,3,2); void setup() { } void loop() { lcd.clear(); int potiVal = analogRead(potiPin); lcd.print(potiVal); delay(500); }
Here's the result. The Arduino displays the poti setting (a value between 0 and 1023) on the LCD display.
This done, I'd consider myself proficient enough to start processing incoming voltages from a directional coupler. Let's no longer worry about the microcontroller. This is all under control and the program shall be written in a few moments. Now I must care for the hardware.
