Made a new version of PEN Holder with few features

The goal was to create a pen stand that was entirely different from the typical pen stand. It would have a number of features, such as a room temperature and humidity meter, an onboard light for aesthetics and illumination, and a USB port that could supply 5V to power various devices, including smartphones.

Version 1 of the PenStand I constructed last year was large and heavy; Version 2 is more compact and has an additional ESP8266 Setup that is connected to an SSD1306 OLED and an AHT10 Sensor.
