My Arduino was working and then it stopped working (Uno). What happened was it stopped uploaded. The upload would start, the lights would flash but it would not finish.</p><p style="margin-top: 1em; margin-bottom: 1em; padding-top: 0px; padding-bottom: 0px; margin-right: 0px; margin-left: 0px; padding-right: 0px; padding-left: 0px; display: block; ">
I was frustrated because I hadn’t changed anything.</p><p style="margin-top: 1em; margin-bottom: 1em; padding-top: 0px; padding-bottom: 0px; margin-right: 0px; margin-left: 0px; padding-right: 0px; padding-left: 0px; display: block; ">
I then decided to try to stop using pins D0-D3. Instead I used D2-D5.</p><p style="margin-top: 1em; margin-bottom: 1em; padding-top: 0px; padding-bottom: 0px; margin-right: 0px; margin-left: 0px; padding-right: 0px; padding-left: 0px; display: block; ">
This hunch came when I noticed D0 and D1 are labeled as Send and Receive.</p><p style="margin-top: 1em; margin-bottom: 1em; padding-top: 0px; padding-bottom: 0px; margin-right: 0px; margin-left: 0px; padding-right: 0px; padding-left: 0px; display: block; ">
I’m happy it started working again but I’m puzzled why it worked inconsistently. Also if pin D0 and D1 are inconsistent, does that mean we shouldn’t use them?</p></span><div><div><br></div><div><br></div><div><br></div><div>
