Measurement of Capacitance using Arduino – An Interrupt-based Approach: Part I SAIKAT PATRA‚ SHIBENDU MAHATA Introduction Capacitive sensors are widely employed to measure various physical and chemical process parameters such as displacement‚ acceleration‚ thickness‚ force‚ pressure‚ stress‚ level‚ and humidity. The measured value of capacitance is then calibrated in terms of the process parameter for indication and/or control applications. This project presents an interrupt-based approach by

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive
