現在是高科技工業的時代。照明系統的使用是非常需要的，如何享受照明與節約能源，對每一個人來說是迫切而需要的。因為節能減碳的需求，使我們必需發展LED 燈照明技術。照明用電占台灣整體用電的百分之20 到百分之25。
本論文學習以PSoC 為核心的LED 觸控調光技術，也做這方面的實驗。學生可以透過CY3268 學習工具學習LED 調光技術，同時也可以學習觸控技術。由本論文實驗結果可以知道CY3268 是很適合初學者的學習工具。
Now, it is the high-tech industry. The use of lighting equipment is essential. How to enjoy the light and save energy are now
familiar to everyone. LED light is small and light. Of course, energy is the main reason we use the LED light. The lighting
consumption is about 20% to 25% of the entire electricity in Taiwan.
The PSoC-based and cap sensed LED dimming are studied in this paper. The experiments are also done in this paper.
The Cypress CY3268 kit shows the scalable LED management solutions and enables students to study LED.
The CY3268 kit includes 4 high brightness LEDs and 5 capsense buttons. Therefore we can also study capsense buttons
by use of this kit. From experimental results, the CY3268 kit is appropriate for beginner.
