The purpose of this research is to know the implementation of Arduino in teaching English for young learners, the advantages and disadvantages of Arduino in teaching English for young learners. Arduino is an open-source hardware prototyping platform that can be used to create programming based projects. It contains pictures, words and sound. This research uses a descriptive qualitative approach. Then for the sample is class B1 and the English teacher of that class. The total of the students are 20 students. Observation, interview and documentation are used as an instrument. Technique of analyzing data is using three techniques; they are reducing data, displaying data, and conclusion/verification. The result of the research show that the implementation of Arduino in teaching English for young learners has three activities. Pre activities, whilst activities and post activities. Greeting, praying, checking students' attendance and explaining the purpose of the meeting are all of the activities in the beginning or pre activities. The teacher demonstrates the implementation of Arduino in the classroom in the whilst activities. Lastly, reviewing and making resume of the material are posted activities. Advantages of the implementation of Arduino can help the students to learn English easily, motivate to learn English, train the students' concentration, and make the students enjoy in the class. There are some disadvantages of this research; first, it takes a long time because the teacher needs more time to prepare and turn the picture. Second, the class become noisy.
