Rancang Bangun Prototype Media Pembelajaran Fisika Berbasis Micro Controller NodeMCU

Abstract

This research is aimed to develop a prototype of physics instructional media based on micro controller. Physics learning media about Newton’s second law prototype has been developed by combining IR sensor obstacle, NodeMCU, and sketch program the Arduino IDE as counter time, and tracking, block, pulley, rope and metal strip as support device. The experimental results show that the value of acceleration of the object on a slippery plane is larger than the rough plane. The results of the analysis of the acceleration and the resultant graph shows that the external force is directly proportional and a graph showing the acceleration vs the object's mass is inversely proportional. Thus we can conclude that Physics learning media based on NodeMCU is valid in explaining and proving Newton's II.
