| The offered code shows the measured values 0-5v = 0-1023 ... |
| For Arduino boards: NANO - UNO - MEGA |
| Arduino pins are used: see connections |
| |
| Electrical note: (Recommendation:Use the following accessories for testing as well as for later use: Lnk1 - Lnk2 ) |
| Note: The measured voltage (A0-A7) must not exceed 5V! To increase the range of measured voltage can use a voltage divider (Link1). |
| Connect each input pin to GND via a 100K resistor (R1-R8). |
| An external 9V power supply (VIN/GND or on DC jack) is required. |

| Download the HEX codes below, unpack and upload to the proper Arduino board (Use a free net tool for example XLoader) |
| 1. uc ATmega328-16MHz (MINI,NANO,UNO..): PCV108-m328 |
| 2. uc AtMega2560 (Mega(ATMEGA2560)......): PCV108-M2560 |

| Description of HexCode commands ( You can test the uploaded code using some free serial communication software such as Termite (select: Append CR)): |
| AT command (ASCII characters + ENTER) - Baud 9600,8 Data bits, None Parity,1 Stop Bit |
| AT - attention command (returns OK) |
| I? - software code info (return ucAppName) |
| RVA - reading status of all values (return Vxx=X (xx=01-08 X=0-1023 (Vinx=0-5V)) |
| RVxx - reading single status value xx (xx=01-08) (returns Vxx=0-1023 (Vinx=0-5V)) |
