Q2 Robotics reviewer

• timer: an integrated circuit (electronic device) that uses an oscillating pulse signal.
• relay: an electro-mechanical device that can control other device or can receive signal from a sensor.
• programmable logic control uses Ladder type programming.
• integrated PLC: it is a fixed program module
• modular PLC: not fixed program and can be modified and expand program.
• microcontroller: an integrated circuit that program can be downloaded to control other devices. Also, the brain of the robot.
• programming language: an encoded machine language instruction that can be downloaded to a microcontroller.
• C++ is the programming language used in Arduino IDE.
• C++ always end a line using semicolon.
• open loop control device: is used for precision level task.
• feedback control: the input signal can affect the output. Such as a sensor that control a motor in line tracing robot.
• IDE: a platform that encode program for microcontroller.
• compiler: part of IDE that check error in the encoded program.
• loader: part of IDE that convert program to machine code to be downloaded to the microcontroller.
• comm error: this error indicated that the microcontroller is not properly connected to the computer.
• board not found: this error indicates that the microcontroller is not set to the type of microcontroller.
• syntax error: using symbol or code that is not recognize by the program language.
• flowchart: a step by step process to give a consistent flow.
• encoding: writing of program on IDE to be loaded to microcontroller.
• compiling/verify: checking for error in the codes.
• loading: downloading the program to the microcontroller.
