Abstract

The aims of this research is to develop a musschenbroek long expansion device digitally by using electic heaters from solder elements and LM35 temperature sensors based on Atmega 16. This research starts from the potential to develop a manual musschenbroek long expansion experiment tools. In the second stage, collect information about digital products that can support the development this tools. In the third stage, carry out the planning of the design and manufacturing of tools. In the next stage, try out the tools dan repairment. The final results of the test obtained the value of the length of the expansion coefficient of eachmetal has approached the theoretical value that has been previously known. Brass expansion coefficient 2,04x10-5/oC; Iron expansion coefficient 1,31x10-5/oC; Aluminium expansion coefficient 2,72x10-5/oC. Due to the simplicity of the experiment tools, it can be used to introduce the concept of metal long expansion in the learning process to high schools students.
