摘要：Experiment activity is an essential part of physics learning because it engages students to interact with real physics phenomena and develop their scientific abilities. However, online physics learning still faces a challenge in providing experiment access to the student. In this paper, we propose an alternative experiment activity to explore Ohm's Law in physics class. The experiment incorporates Arduino and a block-based programming language called Common- Coding Builder (CCB). Arduino Uno is an affordable microcontroller that can be used to measure many physics quantities. Programming using CCB can be carried out by students who have never learned to program before. Hence, the combination of Arduino Uno and CCB offers engaging and affordable experiment activities in online learning.
