The objective of this Final Project Research is to design an instrument that can be used as scoring tools for boulder sport climbing competition by utilizing human body electrical resistances. The boulder scoring system which is used today still have weakness, there is no standard about method and how long a climber need to hold the climbing holder so he/she can get point. By integrating human body as part of voltage divider system, the climbing holder status can be monitored, whether the climber touch the holder or not. Research to several subjects shows that human body electrical resistance has value range between 300 k and 800 k. The designed prototype using four microcontrollers ATMEGA8 as touch sensor module, and one microcontroller ATMEGA8535 as score display controller also as climbing time allocation controller. Communications between microcontrollers using USART protocol in asynchronous mode, with baud rates 9600 and without parity bit. Prototype designed to be able to sense a touch at climbing holder regardless pressure magnitude given to climbing holder. Data transfer each communication process is 8 bit consists of 4 address bits, 2 bits of climbing poin status, and 2 bits of instruction. Climbing scores status for each route updated every 1 second, and showed at display. By designing this <br /> <br /> <br /> instrument, the quality of scoring system for boulder climbing competition will be better than the current one used today.
