Programming PIC Microcontrollers
PIC microcontrollers are a highly useful and versatile component for various electronic projects. They are affordable and readily available.
PIC microcontrollers are embedded systems that serve as the central control unit in a wide range of electronic applications. Their architecture is...
Build a PIC controlled DDS VFO, 0 to 6 MHz
Almost any 2x16 character LCD module with Hitachi HD44780 controller chip will work. The LCD pin numbers on the schematic are not valid for all LCD modules. Please check the actual signal names on your particular LCD module. The selected...
Interfacing to External EEPROM
An external EEPROM is beneficial for various applications as it provides significantly more storage capacity than the internal memory of the 18F4520 microcontroller. Additionally, EEPROM retains its data even when power is disconnected. This project involves interfacing with a Microchip...
Microcontroller interfacing with RS 232
Standard serial interfacing of a microcontroller (TTL) with a PC or any RS232C standard device requires a TTL to RS232 level converter. A MAX232 is used for this purpose. It provides a 2-channel RS232C port and requires external 10µF capacitors.
The...

Metal detector circuit
The project demonstration has been successfully completed, with the only remaining task being the final project report due on June 15, which will be integrated with a conference paper. This update marks the last entry in the electronic notebook, although...
PIC dual Thermometer
This circuit utilizes a PIC16F876 microcontroller, two MCP1047A temperature sensors, an MCP1541 voltage reference, and a MCP6022A operational amplifier. The display is a 2-row HD74780-based 2x16 character display (SII L1652BIJ2), though any HD74780 compatible display can be used. The thermometer,...
analog light dimmer circuit connected to microcontroller
Assistance is required to modify a light dimmer circuit connected to a PIC12C508 microcontroller. This circuit is designed for the...
The light dimmer circuit utilizing the PIC12C508 microcontroller serves to control the brightness of a light source through pulse width modulation...
AVR-P40-USB-8535 BOARD FOR AT90S8535
There are two ways to program AVR-P40-USB: with ICSP port and with JTAG port. To program via ICSP port you need serial port or parallel port AVR-ICSP programmer dongle (Olimex part # AVR-PG1B or AVR-PG2B). The serial port ICSP programmer...
