</p><p>So the Rotary and Timer part will communicate via serial to the Banana Field that is again connected via Serial to the Password &amp; Servo Lock part, that communicate back to the Rotary and Timer, closing the circuit. </p><p>This is quite simple yet optimal communication protocol in Arduino. </p><p>We use TX and RX at the end of each Arduino board, software define as Serial1. </p><p>In order to communicate each Arduino board needs to share the GND. </p><p>So i've actually use a bread board on the back of each panel, in order to tidy up and easily reach the TX,RX and GND of each Arduino board, than i wire up each board to the other using long jumpers connecting each bread board. </p><p> </p><p> </p><div id="gallery"><img id="gallery" src="https://projects.arduinocontent.cc/a4e9fd4a-490a-4b9f-9e2c-0c0559034a46.jpg"/><figcaption></figcaption>,<img id="gallery" src="https://projects.arduinocontent.cc/84a4ea39-9ecc-467f-b3dc-74a840784ea3.jpg"/><figcaption></figcaption>,<img id="gallery" src="https://projects.arduinocontent.cc/28137ebc-10fe-41b2-86c3-f72d5be55d23.jpg"/><figcaption></figcaption></div><p> </p><p> </p><p> </p><p> </p><p> </p><p> </p><p> </p><p> </p></body></html>
