//License: Creative Commons CC-BY-SA-compatible Open Source Ecology (OSE) License //Purpose: for testing Open Source Ecology's CEB Press //Orientation: when you face the CEB Press, the ejection side is to your left //Motion Control: the CEB Press has 5 motions- it can move its primary cylinder up and down, its secondary cylinder left and right, and rotate its shaker motor //Sensors: the CEB Press has 2 hall effect sensors; on the primary cylinder and the secondary cylinder. The sensors switch and latch on and off when magnets move past them. //Test Selection: type true or false for the tests you want to do or not //Timed Movement, One-Time: boolean startdown = false; //Primary Cylinder Down int downtime = 6000; //For how long in milliseconds? boolean startup = false;//Primary Cylinder Up int uptime = 1000; boolean startright = false; //Secondary Cylinder Right int righttime = 4000; //For how long in milliseconds? boolean startleft = false;//Secondary Cylinder Left int lefttime = 1000; boolean startshake = false; //Shaker Motor Spins int shaketime = 3000; //For how long in milliseconds? //Sensor Tests, Repeating: boolean repeatsensor = false; //Want to see the sensor signals without motion? boolean primary trigger = false; //Want to see when the microcontroller "triggers" in response to the primary sensor? boolean secondary trigger = false; //Want to see when the microcontroller "triggers" in response to the secondary sensor? //Sensed Movement, Repeating: boolean repeatprimary = false; //Want the primary cylinder to cycle up and down according to the primary sensor and magnets? boolean repeatsecondary = false; //Want the secondary cylinder to cycle left and right according to the secondary sensor and magnets? boolean operation = false; //Want to continuously press bricks?
