This project is an attention-grabbing interactive installation for an Irish charity community organization-Action Lesotho. It is conducted to exploring how the combination of technology and interactive donation installation might affect an individuals' willingness to donate to a charitable organization. The objective of this project is to communicate the fact that even a small donation can make a big difference. And the aim of this project is to use innovative interactive donation installation to generate donation to provide hot meals and books to the disadvantaged children in Lesotho Africa. Based on the background research, related project and iterative user-centered design process, an interactive installation was built using sensors, Arduino and LED technology. The installation set up on the ground and shaped as a tree. When a coin is donated directly into the installation, the coin will slides slowly along the tracks, which twine around the tree trunk to trigger various Action Lesotho aid projects visually come to life. It is necessary to make people directly aware of the impact that a coin can have.
