![]() I'm putting together a mount for the tablet that lets it sit just behind the dashboard double-DIN frame, and include a small stack of magnets to stick it to the eject mechanism. There's enough room to mount the tablet flush behind the dashboard fascia, but I'd like to find an easy way to move the tablet in and out of my dashboard (to easily remove it for security/use elsewhere). #LINEAR SERVO MOTOR ARDUINO ANDROID#Then connect the servo to the Arduino and run it.So I'm in the process of replacing my car's stock audio setup with a 7" Android tablet and a different head unit. If you’re using a continuous servo, you need to make it vertical, since the rack gear needs to drop down. If you’re building with a 180° servo, you can set both vertical and horizontal directions are fine. Now you just need to set props (part #4). Here you shouldn’t to attach the rack gear together. Once dried, place them on the path, double check if this path fits to the rack gear’s linear motion, and glue them carefully. This process is same for both 180° and continuous servos. Once you’re sure, attach it to the enclosure part #5 and repeat it with the rest using the part # 7 and 8. Because it will complete the path for the linear movement of the rack gear, this space shouldn’t be too loose or too tight. Check whether the part #6 is slightly higher than the rack gear. Now, you need to build the other side of the wall to complete the path for the rack gear. To check the correct position, set the pinion gear as shown at the right before hitting the rack gear and see if it is at the right place to interlock the rack and pinion gears as the pinion gear continues rotating counterclockwise. Cut a small cardboard part (I used the small piece cut out from where the motor mounts on the body case) and place it at the bottom of the path. To use a continuous servo, you need to build a ‘floor’ to place the rack gear after it drops down. Here, an additional part for the continuous servo version comes. Once you’re sure of its path, glue the part onto the body. Attach the long thin part #2 besides the rack gear position.It will make a wall to help the rack gear move straight up and down. Turn the motor clockwise, and plan the bottomline for the rack gear’s linear motion. If you’re not familiar with playing with servo motors with the Arduino controller, start from part A. If you’re familiar with electronics (servo motor control), skip part A. #LINEAR SERVO MOTOR ARDUINO HOW TO#Part A (step 2, 3) shows how to control servo motors, and part B (step 4, 5, 6, 7) shows how to assemble parts to build a linear movement by rack and pinion gears. My instruction is divided into two parts. Glue gun and glue sticks: to attach gear layers and assemble parts.Duct tape: to attach servo motors to the case.A bag of 100 wood skewers costs $1-$2 from supermarkets or craft stores. Wood skewers: I used it to adjust the height in adapting the linear movement to other crafts.1 Cardboard (or formboard): I used recycled box cardboard to build the case.By doing so, it becomes rigid and thick enough to generate the power to pull and push but can still be cut or trimmed with a knife cutter or a scissors. I made a gear by attaching two layers of gear parts using illustration boards. 1 illustration board (or mat board): Both illustration board and mat board can be found in craft stores.A breadboard (if you want to build only one, you don’t need).7 wires (if you want to build only one, 3 wire).2 servo motors (I used standard size of 180° and continuous servos). ![]()
