Now, to know where we are pointing, we need sensors on each axis (azimuth and elevation). Sensor integration: For elevation, I used the Grove 3-axis aen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/summer-of-green-tech-design-challenge/b/blog/posts/blog-4-sunray-bender---development-of-controllerTue, 24 Oct 2023 20:08:49 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6fda3ad7-2c4e-4cca-9a51-404ebda88923DAB0<p>Nice update.</p><img src="https://community.element14.com/aggbug?PostID=27075&AppID=414&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/summer-of-green-tech-design-challenge/b/blog/posts/blog-4-sunray-bender---development-of-controllerMon, 23 Oct 2023 16:14:37 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6fda3ad7-2c4e-4cca-9a51-404ebda88923hitesh.boghani0<p>One issue in this blog I had is that the equation editor didn&#39;t work very well. It didn&#39;t show exactly what I had typed.

The two were joined by a non stretch thin cord kept in tension by a coil spring. If the cord slipped you could wind it round the drive of capacitor shafts more than once.</p> <p>The goal of a nicely set up drive was that you could span the full FM radio range by giving the control known a single flick so that its inertia would drive the capacitor all the way round.</p> <p>MK</p><img src="https://community.element14.com/aggbug?PostID=27075&AppID=414&AppType=Weblog&ContentType=0" width="1" height="1">
