 <WRAP round box 60%>
 ===== Goals =====
   * [OK] Flash Webduino with different IDEs
-  * Use serial Monitor
+  * [OK] Check Components : pins, photocell, RGB LED, button
-  * Check pins, photocell, RGB LED, button
+  * [OK?] Use OTA
-  * Use OTA
 </WRAP>
 ===== Description =====
-  * Webduino USB port is only used to power the board, not for upload and monitoring
-  * The chip is labelled ESP8266MOD by AI Thinker, in fact it is an ESP-12F, same as Wemos d1
   * [[https://webduino.io/en/tutorials/smart-01-information.html|Official Intro]]
