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...

IR On/Off Switch Using Microcontroller

Turning electrical devices ON or OFF using a remote control is a well-established concept, with numerous devices available that perform this function effectively. To create such a device, it is necessary to construct a receiver and a transmitter, as well...

Security Lock with keypad and LCD (PIC16F84A)

Finally I was able to control an LCD Hitachi display and a 12-key matrix keypad with only one 16F84 or 16F628. In a near future, I will be able to control a full QUERTY-type keyboard and a LCD display. The...

synchronizing fireflies ng

This is a remake of the fireflies project that was created a year ago. The concept revolves around the emergence of patterns, particularly the synchronization of hundreds or thousands of fireflies. Initially, they flash randomly, but over time, influenced by...

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...

mosfet Turning a microcontroller on with a flip flop

The objective is to control the power to a load, specifically an 8051-based microcontroller (uC), using two switches. When the uC is powered on, it sets the PWR pin high. Upon pressing the switches again, pin 4 of the flip-flop...

Interfacing seven segment to microcontroller

The Tutorial shows how to interface 7-segment display to a microcontroller. Also explains how do display more than one 7-segment on same data lines using scanning method. 7 Seg displays are are basically 7 LED's. It will be much easier...

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...

Microcontroller based College Automation System

This project is a microcontroller-based college automation system aimed at addressing the challenges faced in educational institutions. It replaces the conventional notice board with an automated device that allows users to both hear and read the information being announced through...
