Access to suitable learning platforms is crucial for motivating learners and making Science, Technology, Engineering, and Mathematics (STEM) an attractive field of study. This study analyze the potential benefit of integrating Microcontrollers into STEM learning in the schools. The responses of participants in the STEM Outreach program is analyzed to evaluate the potential impact in encouraging the rural youths in taking up the STEM fields of study in higher education. Coding on two microcontrollers, namely the runlinc E32W controller and Arduino, was introduced in ten schools, involving 447 students, of which 211 were girls and 236 were boys. The focus was on making them understand and helping them project the larger scope of STEM through developing basic applications on automation, the Internet of Things (IoT), and robotics, particularly on solving local problems through technology interventions. Pre-and post-program empirical data were collected to examine how access to and hands-on learning could influence young learners' decision to pursue STEM as their chosen area of study. To gauge the impact of the hands-on learning experience, the researchers employed a Dependent Sample T-Test, ANOVA, Pearson correlation, and linear regression analyses to predict impact. All the tests indicated a significant positive impact on the influence of appropriate learning tools in STEM interest among the students. Further, the SPSS ANN algorithm predicted the significant impact on students' perception of STEM and its future scopes.
