68HC08 PLL Clock Generator

The program utilizes the built-in analog-to-digital (AD) converter of the PIC16F874 microcontroller for sensing touch buttons. The PIC features eight AD ports, with seven designated for the touch buttons and one for light measurement. To receive DCF signals, a...

Q1 is a fixed oscillator operating at 455 kHz. U1 is a mixer with its own internal oscillator running at 45.5 kHz. FIL1 and FIL2 are Murata CSB455E filters or equivalent. D1 is a varactor diode (an IN4002 used...

It has 16 timers that can be independently paused and restarted, and can run forward or backward. There are 16 alarms with configurable sounds and actions. Timers can show Earth, Mars, Jupiter, etc. times at the same time. How...

This is a square wave generator circuit. The primary component of this circuit is the 741, a general-purpose operational amplifier. The circuit operates with a single power supply voltage (Vs) that can vary between +5V and +15V. The square...

How to create a binary clock utilizing a PIC microcontroller with multiplexing to control an LED matrix. To design a binary clock using a PIC microcontroller, the circuit will primarily consist of the microcontroller, an LED matrix, and multiplexing circuitry....

This simple square-wave generator produces a variable frequency output ranging from 2800 Hz to 80 kHz, as indicated by the specified values. The frequency can be adjusted using potentiometer R1. The square-wave generator circuit typically employs a combination of resistors,...
