Hello, I'm Pyfan. An edit that you recently made to Resistor–transistor logic seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! &mdash; Oli OR Pyfan! 14:37, 8 March 2017 (UTC)
