Password Based Door Locking
Security is a prime concern in our day-to-day life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain. The microcontroller based Door locker is an access control...
knight Rider
A light computer has been developed that simulates the scanning effect seen in the KITT car from the TV series Knight Rider. The design utilizes a microcontroller, specifically the PIC16F84A, instead of the commonly used CD4017 counter IC. This choice...
Some Voltage Regulator Ciruits for Microcontroller based Projects
A regulated and noise-free power supply voltage is essential for microcontrollers and other components such as amplifiers, filters, and GPS devices. Voltage surges in the supply voltage can permanently damage embedded systems. A voltage regulator must maintain the output voltage...
Jet
The microcontroller is able to make about 7000 complete line-following decisions per second, which is almost 7 decisions per millimeter when the robot is going full speed. By upping the clock, unrolling loops, and removing my wireless debugging and extraneous...
Eight-digit-microprocessor-display
The display interface utilizes the ICM7218A/B in conjunction with an 8048 family microcontroller. An 8-bit data bus (DBO/DB7-IDO/ID7) facilitates the transfer of control and data information to the 7218 display interface during successive WRITE pulses. The mode input pins on...
Speed Control of DC Motor using Microcontroller by using PWM ECE Project
This report details an electronic project focused on the speed control of a DC motor using a microcontroller and PWM (Pulse Width Modulation). The system integrates a microcontroller with an LCD, keypad, and a DC motor driver. The microcontroller generates...
microcontroller Generate a reset signal from a falling edge trigger
The microcontroller design features the microcontroller (MCU) in hibernation mode, which can only be awakened by a pulse (high-low-high) signal on the reset pin (active low). An accelerometer or an external real-time clock (RTC) serves as the wake-up source. The...
integrated circuit Improving absolute precision of ADC to balance battery voltage
Utilize a high-performance microcontroller (Piccolo TMS320F28035, 12-bit resolution, +/- 4 LSB offset, +/- 60 LSB gain) to measure the voltage across stacked battery cells and control related analog electronics for charge equalization. The microcontroller will also save data in EEPROM...
delay circuit for photography
This article outlines the construction of a simple microcontroller-based delay circuit designed for photographic applications such as drop or high-speed photography. It can control the trigger lag of cameras and flash units, generate periodic trigger pulses, or manage magnetic valves....
