Despite its size, it has a resolution of 70 by 40 pixels and is connected to an Arduino Uno with only four wires. The chip used for this display is the SSD1306, which is a great choice as it is compatible with many other displays with resolutions of 128 by 64 pixels or 128 by 32 pixels.
PCB Way
PCB Way is a great resource for those looking to manufacture their own products. It offers services such as 3D printing, CNC machining, and other types of manufacturing. The Module Store on the main page also has a variety of products available for purchase, including RGB Glow Tube Clocks which have been tested in previous videos.
Using the u8g2 Library
The u8g2 library is used to draw on the display. When searching for the resolution of 70 by 40 pixels, no display is found. However, when searching for the chip SSD1306, there are several displays with this chip, including those with resolutions of 128 by 64 pixels or 128 by 32 pixels. It is necessary to randomly choose one and test it to see if it works.
Testing the Display
Once the display is chosen, it is time to test it. The Arduino IDE can be used to upload code to the Arduino Uno and test the display. The u8g2 library can be used to draw on the display and check if it is working correctly.
Connecting the Display to the Arduino Board
To begin, the display must be connected to the Arduino board via four wires. The ground wire should be connected to ground, the VCC wire to 5 volts, the SCL (serial clock) wire to either pin A5 or the dedicated SCL pin, and the SDA (serial data) wire to either pin A4 or the dedicated SDA pin. Once the connections are established, the code can be uploaded to the board.
Using the Walkway Emulator
The Walkway emulator is a free, online Arduino emulator that can be used to test the code before uploading it to the board. When the code is run on the emulator, the full-screen image should be displayed on the display. The code can then be copied and pasted into the Arduino IDE and uploaded to the board.
The SSD 1306 Chip
The SSD 1306 chip is the internal memory that holds 128 by 64 pixels. When the display has a resolution of 128×64 pixels, all of the memory must be used. However, if the display is smaller, such as the 70 by 40 pixel OLED screen used in this tutorial, it can choose which part of the memory to use, depending on how it is wired to the chip.
Using Arduino Shield to Test OLED Displays
Arduino UNO and SSD1306 72x40px OLED Display can be used to create a Tiny OLED tutorial for beginners. This tutorial can be used to test the displays with an Arduino Shield. It is possible to switch one of the displays with a small display and verify the results. This can be done by drawing a full screen rectangle on the small OLED screen. The size of the rectangle should be 70 by 40 pixels, with the X position being centered on the 128 pixels (128 minus 70, divided by 2, which is 29 pixels). The Y position should be 40 pixels on the bottom of 64 pixels, which is 24 pixels.
Using Photop to Create Graphics
Creating graphics for the Tiny OLED tutorial can be done using Photop, a free online graphic tool. This tool can be used to create images that can be used in the tutorial. It is possible to create images with different colors, shapes, and sizes. The images can then be used in the Arduino sketch and uploaded to the board. This will result in a full screen rectangle on the small display.

This library is available for download on the Arduino website and can be installed by following the instructions provided. Once the library is installed, you can begin creating your project.
Creating the Project
The next step is to create the project. To do this, you will need to create a composition that is the same size as the display, which is 70 by 14 pixels. You can then drag your image with the battery outline onto the composition. To create a fill part, you will need to create a new, solid layer that is 30 by 34 pixels and position it on the left side. You can then apply the layer style being the outer glow, which should be white and the technique should be precise with a size of 8 pixels.
Adding the Particle
The next step is to add the particle. To do this, you will need to create a new ellipse and apply the same outer glow effect to it. Finally, you will need to use a threshold effect, so you will need to create a new adjustment layer and then apply the threshold effect to it. However, this may not make any difference as the composition is transparent. To fix this, you will need to create one more layer that is the same size as the composition and is black. This layer should be moved all the way to the bottom. You can then increase the value for the threshold effect to around 140 and scale down the fill part to 88 pixels.
Testing the Project
Once you have finished creating your project, you can then test it to make sure it works correctly. To do this, you will need to connect the Arduino UNO board to the SSD1306 72x40px OLED Display and upload the code to the board.

Creating the Animation
The next step is to create the animation. This involves creating an array of images to be displayed on the OLED display. The images should be 32×34 pixels in size and should be stored in the array. Once the array is created, a helper array should be created to store references to the individual images. This will make it easier to draw the images on the OLED display.
Drawing the Images
Once the array is created, the images can be drawn on the OLED display. This is done using the u8g2 library’s drawing BMP function. The function requires the array name and the index of the image to be drawn. The size of each image should also be specified. The Y position should be set to 27 and the X position should be set to 32 plus the width of the box.
Animating the Images
The final step is to animate the images. This is done by creating an animation frame variable and setting it to 0. The animation frame is then incremented by one after each image is drawn. The animation frame should not exceed 30, which is the maximum number of images in the array. This is done by using the modulo 30 operator.
Hardware Setup
In order to use the Arduino UNO board and the SSD1306 72x40px OLED display, one must first connect the display to the board. This can be done by connecting the VCC pin of the display to the 5V pin of the Arduino UNO board, the GND pin of the display to the GND pin of the Arduino UNO board, the SCL pin of the display to the A5 pin of the Arduino UNO board, and the SDA pin of the display to the A4 pin of the Arduino UNO board.

Once the u8g2 library is installed, one can begin to draw on the display. This is done by writing code that calls the u8g2 library functions. For example, one can draw a line on the display by calling the drawLine function. This function takes four parameters, which are the x-coordinate of the starting point, the y-coordinate of the starting point, the x-coordinate of the ending point, and the y-coordinate of the ending point.
Fixing the 2 Pixel Gap
When drawing on the display, one may encounter a 2 pixel gap between the image and the background layer. This can be fixed by calling the setBitmapMode function and the setClipWindow function. The setBitmapMode function takes one parameter, which is the mode to set the bitmap to. The setClipWindow function takes four parameters, which are the left and upper edge, and the right and lower edge. By setting these parameters, one can ensure that the image is drawn within the specified area and the 2 pixel gap is eliminated.
