Open Hardware Monitor with Arduino and Nextion

Welcome to my little side project!

We're going to make a uncomplicated hardware and sensor monitoring tool that looks peachy as a built-in slice of hardware or equally a gadget on your desktop!

Working principle:

Read the data from your Laptop/PC -> transport it to an Arduino that only forwards it to a Nextion display!

Adept to know before starting:

1. The core app is based on Open up Hardware Monitor - it needs admin rights to read some temps and info

ii. The Arduino acts only every bit a serial data forwarder to the display

it can exist connected via USB
directly to the motherboard USB pins

3. Information technology works with the ii famous displays: Itead's [Nextion](https://nextion.tech/enhanced-series-introduction/) and information technology'due south original Chinese equivalent of TJC

currently the user interface is created for the post-obit 2 models: NX4832K035_011, TJC4832K035_011

Naming convention:

NX - Nextion
4832 - 480 x 320 resolution
Grand - ENHANCED family
035 - 3, 5inch screen size

Page layout / Features:

Status1:

CPU temp/load
GPU temp/load
RAM usage
GPU RAM usage

Status2:

HDD1 proper name/used space
HDD2 proper noun/used space
GPU fan usage/RPM
CPU Power consumption

Graph:

CPU & GPU temp - long-term representation

Settings:

Show/Hide either the CPU or GPU temp
Colorize CPU temp based on it's values
Modify GPU colour to a custom color

Info

Minimal info about the motherboard, CPU, GPU, HDD1, HDD2, RAM

Settings

Manually change the display's effulgence
Change when the display goes to sleep
Restart the display
Show time and appointment

Other features:

The executable requires admin priviledges, equally the Open Hardware Monitor library needs to read the sensor data (don't worry about that) :)
The brandish turns off after 1min, if it doesn't receive data
To manually plow off the display, merely printing "Lock" on the primary page
Only 2 storage units are handled, information technology should exist enough
Send custom commands to the brandish (ex. slumber=1)

How to get started:

1. Wink the Arduino with SimpleSerialReader.ino

2. Flash the precompiled *.tft file for your display

3. Impress the display bracket

4. Connect the display to the Arduino: 5V to 5V, GND to GND, RX is pin 12, TX is pin eleven

5. Run the executable

Select the correct COM port
Select baud rate (unremarkably 115200)
Choose update rate - works fine with 2000msec

Cheque out the resources and the project folder on my Github page! Here are some tips for future improvements:

                                  [10] Characteristic to minimize the app to the taskbar                  
                  [x] Feature to select which data has to be sent to the display                  
                  [x] Send custom commands to the display                  
                  [ ] Add autostart with Windows! - I just started C#, the app tin be improved in many ways                  
                  [ ] Create different themes for the user interface - the display can accept many themes, and then information technology matches your surroundings!                  
                  [ ] Extend the functionality - other external libraries tin can be included - such equally fan control or RGB light control!
