Adding the Pan/Tilt Camera and Raspberry Pi Zero
Warning! Make sure you have set up your servo as seen in the last step of the Pan Tilt Mechanism section of the Basic guide! Failure to do so may allow the servo to fall forward, damaging parts of the RVR.
Assembling the Pan-Tilt Mechanism Hookup Instructions |
Once the horn is mounted in place, you can use the larger self-tapping screws to mount the pan-tilt rig. It’s important that the rig is mounted so that the middle of the servo travel faces forward. This will take some trial and error, but you want the servo to be able to move an equal amount in either direction when facing directly forward (it’s okay to move the servo when it isn’t powered, just don’t force it).
Add the Pi Zero W (with the spacer nuts installed) to the mounting plate with another 4 of the 4-40 nuts. For the best access to all the connectors on the Pi Zero, make sure the USB and HDMI Connectors are facing the back of the plate and the pins are facing the pan-tilt rig.
