| LDP211210: Timer with settings Time1 & Time2 (0,1-999,9sec.) started on S1 and 2 outputs - TryHex |
| The offered code enables: Start the Timer by pushing and releasing S1. Out1 active for set Time1 and Out2 for set Time2 |
| For Arduino boards:: NANO -- UNO -- MEGA |
| |
| Electrical and practical notes: |
| Uses 9V/1A external power supply (VIN/GND) on DC plug (or external 5V/1A on 5V/GND pin). |
| For stable working use: R1-R3 = 3,3K - 4,7K |
| Display of the measured value is in the form of one decimal digit. |
| Use specified type of 7 segments display with decimal points only (not clock dots). |
| Each output can also drive other type of loads (instead relay module as show on connections) up to 5V/20mA (small or medium power SSR or similar) |

| User guide manual: |
| After applying to the power (or reset), the display shows (----) about 3 sec. During that time: |
| DEFAULT reset settings: Press both buttons (PB1+PB2) and when the screen turns off release. Be sure to do it (only once) after uploading the hex code in Arduino! Default values: P10=5 P12=1 |
| PRESET values settings: Press the PB1 button and when the screen turns off release: |
| P10: Display brightness intensity (0-7) |
| P12: no function yet |
| |
| SETtings (during normal operating - all changes stay memorized): |
| SET Time1 (SV1): Press the PB1(+) button (until the display goes off then release). The value that can be changed on the buttons (PB1/PB2=+/-) is displayed. After 2 seconds of inactivity, the value on the display is stored. |
| SET Time2 (SV2): Press the PB2(-) button (until the display goes off then release). The value that can be changed on the buttons (+/-) is displayed. After 2 seconds of inactivity, the value is stored. |
| Status of outputs: |
| Out1: Active whan push & release PB3(S1) button (for the set Time1). |
| Out2: Active after the set Time1 has elapsed (for the set Time2 (if>0)). |
