Hello, I'm Simplexity22. An edit that you recently made to Light-emitting diode seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think I've made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! Simplexity22 (talk) 20:07, 1 September 2017 (UTC)
