I’m working on a robot project and one of the intended uses is to teach line following to college students. For this, I’m making an array of 9 RPR-220 reflectance sensors. This post will describe the part I’ve designed and the reasoning behind it. It’s a bit rambly so consider yourself forewarned.

Using the RPR-220 and a Breakout Board
One of the projects I’m working on is a robot that has reflectance sensors around its circumference. I had trouble finding sensors that would work in the 0.25-0.75 inch range but eventually found the RPR-220. To mount this sensor, I made a breakout board with space for resisters and connections for positive, negative, and signal. Continue reading “Using the RPR-220 and a Breakout Board”
