Distance learning in physics is still facing challenges, mainly due to the difficult access to a laboratory for practical work. Practical work is an essential part of the physics classroom because it allows students to interact with authentic physics phenomena and develop their scientific abilities. In this paper, we propose alternative experiments that can be carried out at home with affordable apparatus. We explain the use of an Arduino UNO board and block-structured programming environment to design physics experiments about investigating light-emitting diodes and capacitor characteristics. Block-structured programming in the common-coding builder is used because it has extensive features such as plotting data in a graph directly and programming the Arduino board. Moreover, a user with no prior knowledge of programming can use it easily.
