PIC Based RS485 Multiplexer
I decided to implement this using a PIC 16F84 for both an encoder and decoder, and use RS-485 drivers (DS26C31 and DS26C32) to drive the 350m cable. I only needed five I/O pins per PIC, so this could have been...
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...
PIC Current Limiter
The PIC/Generation 1 electronics lack any form of current limiting. They depend on the resistance of the stepper motors to maintain the current below 2 Amps at 12 Volts. Unfortunately, the more commonly available stepper motors of the size used...
PIC Projects
The 12F629/675 PICs are compact 8-pin DIP devices suitable for various applications. They feature an internal oscillator, a comparator, an analog-to-digital converter, and timers. The Microchip PICkit1 serves as an effective USB programmer. PicBasic Pro (PBP) is a user-friendly package...
PIC CW Temp Circuit
Remotely check the temperature of various items, specifically the repeater site at GB3PY. This system utilizes a radio to receive requests for the current temperature and sends the results back to the user. Requests are made using DTMF tones, and...
Microcontroller Relay Driver and Interface
Many microcontroller designs typically integrate various interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs.
Microcontroller systems are versatile platforms that facilitate the integration of multiple interfacing methods to interact with various peripherals and...
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...
OSCCAL Value Finder Board with 16F88
The program loaded in the 12F675 device which has no osccal value will force a pulse on GPIO.4 and it will make a loop while increasing the osccal value internally. GPIO.5 will send the current osccal value used for each...
parallel PIC
The purpose of this project is to construct a computer that utilizes the combined computational power of multiple microcontrollers (MCUs). All MCUs collaborate to solve a single problem. This computer is classified as a parallel processing machine, and the algorithms...
