Based on SSD1306 module, we can display animated images the same as displaying animated GIF on PC. The animated image is a byte array contains (n) number of frames(bitmap images) they all have the same size. the function displays these frames one after another so we see them animated.

SSD1306 Progress Bars

Based on SSD1306 module, we can implement horizontal and vertical progress bars. These bars could be drawn at X1-Y1 to X2-Y2 like drawing rectangles, also we need to pass the full scale value(max value) and the recent value. this code example draws horizontal progress bar at 0-15 to 100-22 with full scale value of 100, and displays value of 78. The vertical progress bar works the same as horizontal one, but it displays the values vertically. HBAR and VBAR modules included in SSD1306 update link above.

rVL53L1X library

This wraps the VL53L1X library by Pololu. The library makes it simple to configure the sensor and read range data from it via IÂ²C.

Updated Hardware serial library for Arduino

Allows CTS/RTS hardware handshake. It''s a drop-in substitute for serial library you can found in Arduino, nothing to wrap or change.

GY-530 / VL53L0X Time of Flight (ToF) laser ranging sensor - Inline C

SubName: Using Time of Flight (ToF) laser sensor to measure distances. Description: A ToF laser ranger sensor is an Infrared (IR) distance measurement sensor, the module uses I2C Bus communications (mine is at 0x29) and can be powered by either a 3.3V or 5V power source. The ToF sensor can measure distances between 30mm and 2000mm (30cm to 2m) with an accuracy of Â± 3% (apparently). This module can detect the ToF, or how long the emitted light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. PLEASE NOTE: The internal laser emits 940nm wavelengths of non-visible light and does not harm the eyes, but if you use your phone camera you can see the light on your screen.
