A Scenix (and PIC) Programmer circuit

A simple home project can quickly become problematic if it encounters electric cables, gas, or water pipes, or the central heating system. Using a metal detector allows one to check for metal objects within walls, ceilings, or floors beforehand. An...

PIC Analogue Synthesizer

A real analog synthesizer to build using easy to get components, capable of a wide range of sounds. The two oscillators can be detuned for that classic synth sound. Dual oscillator mono synth. Really easy to build using just 1...

Driving circuit schematic

The driving circuit depicted in Figure 18-12 consists of a connection between the driving portion, the microcontroller, and the air conditioning operation components of the bridge. The microcontroller's digital signal levels from ports P4.0 to P4.3 (approximately 12 feet) and...

microcontroller driving 4x7 segment display pic 2

A circuit is being designed to drive a 4x7 segment display using a PIC microcontroller. The previous implementation utilized four pins to control each of the four digits individually, with a sequential activation method. The designer aims to simplify the...

PIC Tone generator

This program uses an 8 bit DAC along with a 16F84 PIC microcontroller to generate a keyed sine wave. The 16F84 uses an RC clock which can be varied (with a suitable potentiometer) to allow a variable frequency control for...

What is Microcontroller / PIC programer

Instructions for constructing and utilizing a basic PIC programmer using readily available and inexpensive components. The total cost for building the programmer is under $1.50. The simple PIC programmer is designed to facilitate the programming of PIC microcontrollers, which are widely...

hit the number

A PIC microcontroller is utilized as a keypad driver, along with additional components for functionality. When the timer expires, the keypad is disabled, and an audible beep is activated. When the correct button is pressed, the score counter increments, and...

Microcontroller

The gap between TTL (Transistor-Transistor Logic) devices and personal computers can be effectively bridged with modern microcontrollers. These microcontrollers not only incorporate a central processing unit (CPU) but also include program and data memory, EEPROM, input/output (I/O) ports, timers, and...
