Debouncing is all about making sure that you and the microcontroller agree about when a button push or release event happened. Here’s some oscilloscope plots of me pressing and releasing a ...

Mechanical switches play an important role in many microcontroller and microprocessor applications. These types of switches are simple, inexpensive, and easy to install. But, the perceived simplicity ...

In our minds and our computer screens, we live in an ideal world. Wires don’t have any resistance, capacitors don’t leak, and switches instantly make connections and break them. The truth is, though, ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

Automotive applications need “smarter” drivers for their switches, which handle loads ranging from a fraction of an ampere to several amperes. Not only are these smart chips costly, but many times, ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
