![]() The machine guns can dish out significant damage, killing unprotected humans like Chell after a few seconds of continuous fire. When they spot a target it takes a moment to deploy its weapons to fire. ![]() I would love to hear of any improvements and uses for your Arduino Portal Turret! With Halloween right around the corner I am tempted to connect mine to my stereo amplifier and hide it near the porch to have it greet unwary trick-or-treaters. Sentry Turrets, when idle, conceal their weapons under the two plates on either side of their body. Just make sure you share your adventure with me. Portal turret will audibly call out to user and announce state transitions.įeel free to enhance or change the code as you like. ![]() I am listing the components I used here as a point of reference.Īrduino_Portal_Turret.ino (Version 1.0) – Supports target detection, tracking and acquisition within 180 degrees of the forward position. Parts Listįeel free to source the parts from wherever you like. I cherry picked the sounds I wanted and renamed them to something more meaningful in my source code. Portal turret sound files were obtained from. A wave board is used to play the various portal sounds. Replicates the behavior of a Portal Turret using a PIR Sensor to detect infra red motion (to wake up sleeping turret), a PING Sensor and Servo (to locate target within a predefined distance of the turret), a bright red LED (to simulate the laser designator – much safer then using an actual laser). Though deadly, they are cute little buggers and with a little Arduino magic I set out to create one or more accurately emulate its behavior. One of the cute little obstacles you will encounter are Portal Turrets which stand sentry in various locations happily waiting to shred you to tiny little pieces with their machine guns. It’s this simple mechanism that allows for some brilliant and challenging abstract game-play. Walking through a blue portal allows you to appear wherever the orange portal is (and visa-versa). inter-dimensional doors – one orange and one blue) in walls ceilings and floors. This gun does not fire harmful projectiles but rather allows you to open portals (i.e. It’s a fantastic first-person shooter puzzle game where your goal is to make your way across a test chamber (starting from the entrance and working your way to the exit) using a portal gun. The soundtrack for Portal is contained in the The Orange Box Original Soundtrack released on December 21, 2007. And one of the neatest little games to come out in a while is Portal (and more recently Portal 2).
