This website lets you upload an image, then in 'canvas size' put the dimensions as shown below. <figure><img src="https://projects.arduinocontent.cc/8d26e82a-1be4-4db7-ad34-fc614866a1f3.png"/><figcaption></figcaption></figure>Next, you can change the brightness threshold so your displayed image isn't washed out or so dark you can't see anything. <figure><img src="https://projects.arduinocontent.cc/16eb24cf-bb62-4821-969e-95ea71e222f8.gif"/><figcaption></figcaption></figure>Next, now that you have the brightness threshold and canvas size right you can create the sketch. You will want to create the code in raw bytes. <figure><img src="https://projects.arduinocontent.cc/d402ccc0-9f0c-4502-8b3c-8d2b2558aa0c.png"/><figcaption>You want the type of code to be 'raw bytes'</figcaption></figure> Now that you have the code ready, all you want to copy is the bytes as shown below.
