摘要：Now is a great deal in the entertainment world, especially in a quiz show, agame that relies on speed in answering questions. Way by the participants raisedtheir hands was considered ineffective because it could confuse the jury indetermining who is eligible to answer questions. From this description theauthor got the idea to design tools keystrokes as a response to the speed inanswering questions. This tool uses the AT89C2051 microcontroller circuitcontrolling the work process, in which given an Assembler language program.Assembler language program is compiled using the application in ASM51 andthen downloaded into the microcontroller. Through this program the appliance iscontrolled by three button interface as input and three LED display as arepresentation from the key, accompanied by the sound of a buzzer as anindicator of the LED display lights up.. This tool also comes with two buttonsstart / reset function to reset the microcontroller program can be given the nextinput.
