Protect Your MCU Design from Copying and Reverse Engineering

MCUs are used as the main control element in just about every application imaginable. Their power and flexibility make them the go-to component at the heart of most designs. Since it is important to make sure that your design cannot be easily copied, reverse engineered or tampered with, modern MCUs now provide a few different options for protecting your design; a good understanding of the capabilities and t ...

Digital Code Lock using Arduino with LCD Display and User Defined Password

We have published a digital code lock using arduino some weeks before. This one is a little different. The earlier version was based on a defined password, where the user can not change it. Moreover there was no LCD display interfaced with the project to output lock status. This project is a much improved version of the same digital code lock which comes with a user defined password and LCD display. The use ...

Shower Monitor Arduino with LCD display

Welcome! For our Environmental Capstone class (senior thesis) for St. Olaf College we built a monitor that would effectively monitor how much water a shower uses. The idea behind this water monitor is that if you attach a piezo transducer (small microphone) to a shower pipe, you can calibrate the average of the vibrations while the shower is turned on, and from there you can see how much water you're using ...
