PC stat monitor using ESP8266/Arduino

There are tons of PC applications you can install on your PC for monitoring essential stats for CPU, disk, memory, system temperature, etc. Here is a standalone hardware project that would receive the PC stat via USB port and display it on a dedicated 2.8″ TFT display. The project uses an ESP8266 hardware and a touchscreen-enabled ILI9341-based color LCD. On the PC side, a Python script gathers PC stats and send the data to the ESP8266 via USB-UART interface. With the built in WiFi capability of ESP8266, the PC stat can also be broadcasted over WiFi to a remote cloud server. The firmware is developed using Arduino IDE, so the standalone LCD version of this project would still be compatible with Arduino boards.

PC stats on a tiny OLED

Rupert Hirst bought a new Nvidia GTX1080 graphics card, and in order to monitor its performance, he built an external PC stat display using an Arduino Pro Micro and a 128×64 pixel I2C OLED display. Note that unlike in Arduino Uno, the I2C pins on the Pro Micro are available at the D2(SDA) and D3(SCL) I/O pins. In order to minimize the footprint of his project, he directly hooked the 4 pins (VCC, GND, SCL, and SDA) of the OLED display to the 4 I/O pins in a single row (D5, D4, D3, and D2) of the Pro Micro to minimize the footprint of the project. Because the OLED only consumes ~19mA current during operation, he was able to power the display by pulling D5 High(5v) and D4 Low(to ground).
