        # ArduDAQ

![Alt text](docs/pictures/1.png)

## Project Description

ArduDAQ is an open-source data acquisition shield for the popular Arduino platform with design to measure voltage, current, and onboard temperature with access to the rest of the pins from the base board. 


It's a fun side project to get more familiar and pratice HW and SW before starting a stand alone board. Component selection is somewhat sub optimal as i wanted to use components i had on hand.

## Features

- Multiple voltage measurement channels (16 bit ADC)

- Current measurement channel (10 bit ADC - for now)

- Onboard temperature sensing

- IO (PWM included)

## Testing

| Function         | Status          | Comments            |

|--------------------|-----------------|---------------------|

| Voltage Channels   | ✅ Tested        | Initial test seems good. |

| Current Channel    | ✅ Tested        | Works relatively well but accuracy for super low currents not the best due to use of internal adc which is only 10bit.|

| Onboard Temperature| ✅ Tested  | Initital test seems good.  |

| IO | 🟡 Limited| Switching on 5/7 outputs. 2 dont work as IO due to them being Tx/Rx pins -> will be chnaged for V2 |

| Desktop APP | 🚧  WIP  | Works but needs optimizing. |

Above tests were just the basic tests on the bench.

More detailed testing will be done after the test jig is finished.

Too test the Voltage channel accuracy i teste accuracy so that I measured voltage on the PSU where i was incrementing the ouptu by 0.5V. For a reference point i was also measuring the output with a OWON XD1041 multimeter.

As seen above on the cannel i was testing the accuracy was pretty good, with a max deviation of 8mV @ 50V compared to the multimeter.

## Dekstop App

Alongside ArduDAQ shield's support for serial commands for automated measurements it also has a desktop app(***still WIP***).


It will be able to put the ArduDAQ in continuous mode to display measured voltages on selected voltage channels over time and plot those measurements.

## Getting Started

### Serial Communication

- **Baud Rate**: 115200

- **Data Bits**: 8

- **Parity**: None

- **Stop Bits**: 1

- **Flow Control**: None

### Supported commands

| Command | Description | Response Format |

|---------|-------------|-----------------|

| `info` | Displays available commands via serial | `` |

| `READ_CHANNEL_1` | Read Voltage Channel 1 | `` in V |

| `READ_CHANNEL_2` | Read Voltage Channel 2 | `` in V |

| `READ_CHANNEL_3` | Read Voltage Channel 3 | `` in V |

| `READ_CHANNEL_4` | Read Voltage Channel 4 | `` in V |

| `READ_CURRENT` | Read current draw | `` in A |

| `READ_TEMPERATURE` | Read Onboard Temperature | `` in °C|

| `SET_3_ON` | Sets shield D3 pin HIGH | Pin D3 set to HIGH |

| `SET_3_OFF` | Sets shield D3 pin LOW | Pin D3 set to LOW |

| `SET_4_ON` | Sets shield D4 pin HIGH | Pin D4 set to HIGH |

| `SET_4_OFF` | Sets shield D4 pin LOW | Pin D4 set to LOW |

| `SET_5_ON` | Sets shield D5 pin HIGH | Pin D5 set to HIGH |

| `SET_5_OFF` | Sets shield D5 pin LOW | Pin D5 set to LOW |

| `SET_6_ON` | Sets shield D6 pin HIGH | Pin D6 set to HIGH |

| `SET_6_OFF` | Sets shield D6 pin LOW | Pin D6 set to LOW |

| `SET_7_ON` | Sets shield D7 pin HIGH | Pin D7 set to HIGH |

| `SET_7_OFF` | Sets shield D7 pin LOW | Pin D7 set to LOW |

### Example Usage

To read the voltage on Channel 1, send the command `READ_CHANNEL_1` over serial. Board will respond with a message like: `3.30V`
