Remote Controlled Arduino Car by Kevin Mercer http://www.KevinRMercer.com Overview: This Arduino car utilizes four continuous rotation servo motors to achieve quick, accurate movements and a tight turning radius. An infrared remote and receiver allow the driver wireless operation. The car is designed to be laser cut from 1/8 inch (.125 inch) plywood or acrylic sheet. As all of its components are connected with finger joints, no glue is required; instead, the chassis is held together with four 3D printed clips. Additionally, the car requires twelve* machine screws and nuts, which are listed below. The code is easily modifiable to adjust the car's speed, turning degrees, and continuous driving distance. Predefined actions include forward and reverse driving, 90 degree turns left and right, a 180 degree rotation, and a "dance". Additionally, the car is able to drive forward continuously until interrupted by a stop function.

This will ensure that the details of a particular component are correctly placed prior to cutting out that component. -The top and bottom panels are labeled T. and B., respectively. The lefthand outer panel is labeled L.O., and the righthand outer panel is labeled R.O.. All but the front and rear panels have arrows indicating their forward orientation. The front and rear panels are interchangeable. -Lightly sand the servo-shaped holes with an emory board prior to installing the motors. The fit is tight, as it should be, but forcing a motor into place may crack the plywood or acrylic. -Each servo is meant to fit in its hole only one way. You will notice a small notch cut for the servo's three wires. Note that only one screw is required per motor. -Once each servo is fitted, you will need to enlarge the hole on its ''wing'' to 1/8 inch (.125 inch) large. The plastic is soft enough to drill by hand with the appropriate drill bit; exercise caution if you use a drill for this step as damage can be caused to the servo. -Each wheel is comprised of three stacked 1/8 inch (.125 inch) layers of plywood or acrylic. An .STL of the full-width wheel is available for download if you would prefer to 3D print it instead. Should you use a 3D printed wheel, you will need to pre-drill holes for the servo horns. The provided servo screws may work for attachment, but two 1/2 inch (.5 inch) 4-40 machine screws per wheel may be necessary. Similarly, an acrylic wheel will require pre-drilling; a plywood wheel will not. Because of this, the plywood wheels are the easiest to install. -Any cross-shaped or circular servo horn will work. Each wheel should only require two servo screws for attachment. -If your car seems to get too little traction on slick floors, add a rubber band to each wheel. A 3 inch by 1/4 inch (.25 inch) band will work well. -If your infrared receiver does not receive signals from odd angles, a second receiver can be added. This will require splitting the circuit in the same fashion as either the lefthand or righthand servos. -Continuous rotation servos may require "zeroing". If a motor rotates when it should not, adjust the small Phillips screw on its bottom side until the motor stops rotating. -Your infrared receiver should show three lettered pins: "G", "R", and "Y". "G" = Ground. "R" = 3.3v. "Y" = Signal. -The provided .INO prints your infrared remote's hexadecimal codes in the serial monitor, so you can identify each button's corresponding HEX code. Use this to establish which buttons will drive the car and in what directions. https://youtu.be/uCo3nz9ylbg
