IR OnOff Switch Using Microcontroller circuit

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...

Electronic TIC TAC TOE

This project is not to introduce Tic Tac Toe. Everyone knows this game. It is to introduce two features: bi-coloured LEDs, microcontrollers, and the skill of writing an ALGORITHM. You can use the project to learn the skills of creating...

AVR Inductance / Capacitance meter

This instrument requires two precision components: A precision capacitor and a precision inductor. You only need to start with one precision component, either the reference capacitor or the reference inductor, and using this meter, you can select or adjust the...

16x2 LCD Display Custom Characters Circuit

The schematic for this tutorial is illustrated below and includes all necessary components for the tutorial to function. The PIC programming circuitry is not included, as it is assumed that the PIC is either programmed externally or that the user...

How to handle digital input/output(I/O) in Avr Microcontroller

How to handle digital input/output (I/O) in AVR microcontrollers is explained using basic programs and circuits to illuminate an LED, generate a stepper motor sequence, read a push-button switch, and implement key debouncing. The handling of digital I/O in AVR microcontrollers...

avr ntp clock 2x.

The Network Time Protocol (NTP) has transformed global timekeeping, enabling accurate date and time retrieval from anywhere in the world. NTP is a straightforward UDP-based protocol that can be implemented in microcontrollers. The Tuxgraphics NTP clock has gained popularity over...

LCD Module in 4-bit Mode

In many projects, alphanumeric LCDs driven by Hitachi's industry-standard HD44780 controller are utilized. These displays can operate in either 4-bit or 8-bit mode. In 4-bit mode, only the high nibble (D4 to D7) of the display's data bus is employed....
