interrupts interfacing with pic16f877a slicker circuit

For the past year and a half, a group based in Ann Arbor, Michigan, named GO-Tech has been formed, uniting individuals interested in creating projects using technology, such as hardware, software, metal, and wood. This initiative is referred to as...

using microcontrollers

This schematic illustrates the placement of a decoupling capacitor on the right side, which should be positioned as close as possible to the power pins of the microcontroller. It includes a crystal oscillator, which is optional; an internal RC oscillator...

IR On/Off Switch Using Microcontroller

Turning electrical devices ON or OFF using a remote control is a well-established concept, with numerous devices available that perform this function effectively. To create such a device, it is necessary to construct a receiver and a transmitter, as well...

DIY kinetic energy harvester

A DIY kinetic energy harvester utilizing the electromagnetic method to generate electricity. The materials that will be used are currently known. The project involves creating a kinetic energy harvester that converts mechanical energy from motion into electrical energy through electromagnetic induction....

Multitasking Pins

It is entirely logical that low-cost miniature microcontrollers have fewer pins than their larger counterparts, sometimes too few. Consideration has been given to how to economize on pins by making them perform multiple functions. One approach is to exploit the...

Perfect Pitch Circuit

Perfect Pitch, which is based on the 8751 microprocessor, is an affordable and straightforward instrument tuner and frequency counter that features a built-in headphone amplifier and a visual metronome. Perfect Pitch converts the audio signal from an instrument into a...

AirBorn Electronics project

Embedded system design engineers create examples of their work from the 1990s era. Embedded systems have evolved significantly since the 1990s, and the design work from that period reflects the technological limitations and innovations of the time. Engineers in this field...

Cipher scheme of the module of infrared remote-control between two parties of intellectual family

This system is a control system based on a single-chip computer that allows for remote operation of lighting. The scheme primarily addresses the transmission and reception of signals, as well as program manipulation of various signals once they are processed...

Microcontroller Clapper Switch

For those who prefer convenience, it is possible to turn the bedroom light on or off without leaving the bed simply by clapping hands. This concept inspired the design of a clap-activated light control system. Various clap switch projects can...
