/challenges-projects/design-challenges/summer-of-sensors-design-challenge/b/blog/posts/intellilight-part5RecapFor those of you joining the show late, welcome aboard! For those of you returning for a 5th time, wow, thank you! Just to recap, this is my fifth blog in the Summer of Sensors Design Challenge kindly sponsored by Element14 and in my case Vishayen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/summer-of-sensors-design-challenge/b/blog/posts/intellilight-part5Thu, 13 Oct 2022 21:46:35 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:8a29242b-53ce-4486-8bdf-0e8fda8e08a7DAB0<p>Nice update.</p><img src="https://community.element14.com/aggbug?PostID=24563&AppID=381&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/summer-of-sensors-design-challenge/b/blog/posts/intellilight-part5Thu, 13 Oct 2022 14:52:49 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:8a29242b-53ce-4486-8bdf-0e8fda8e08a7DeltaPi0<p>Looks nice.</p><img src="https://community.element14.com/aggbug?PostID=24563&AppID=381&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/summer-of-sensors-design-challenge/b/blog/posts/intellilight-part5Thu, 13 Oct 2022 00:02:14 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:8a29242b-53ce-4486-8bdf-0e8fda8e08a7Jan Cumps1<p>Nice.&nbsp;</p> <pre>&quot;<span>There is a note about requiring to have external resistors on the I2C lines. However, the ESP has configurable pull-up resistors, so no external circuitry will be required at all&quot;</span></pre> <p><span>External pull-ups are required for i2c. It may work with the esp32 internal ones, but&nbsp; you operate out of spec.</span></p><img src="https://community.element14.com/aggbug?PostID=24563&AppID=381&AppType=Weblog&ContentType=0" width="1" height="1">
