Comparison of the Design and Implementation of Smartphone Charging Controllers using Arduino Leonardo and Raspberry Pi

The main aim of this research is to design an Innovative smartphone charger using Innovative Raspberry Pi for mobile phones. Materials and methods: Designing an innovative smartphone charger system using Arduino Leonardo with 18 samples compared with the power management system using Innovative Raspberry Pi controller with 18 samples. The alpha is 0.04, beta is 0.03 and the g-power is 0.8. Users set the time that would like to charge their mobile. Once the time is reached, 5v relay disconnects the power supply to the charger and the significance value is 0.167($\mathrm{p}\gt0.05$), hence it is observed that the two groups are not statistically significant. The results show that the Innovative Raspberry Pi controller gives significantly better accuracy than the Arduino Leonard.
