microcontroller How does this power supply circuit work? (MCU + LM317)
The filter consisting of resistors R1, R2, and capacitor C1 integrates the PWM waveform. The purpose of the operational amplifier appears to be that of a non-inverting amplifier, with the gain determined by resistors R6 and R7. However, the need...
Power supplies for microcontroller based projects
This document discusses the use of small microcontrollers, such as those from the PIC and Atmel series, which typically operate at 5V and require less than 100mA for complete system functionality. Some PICs can function at lower voltages, such as...
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...
ON/OFF button using Microcontrollers
Using a switch to power up your microcontroller projects may not be a good idea if you need to "wake" the PIC during some events. For example: A metal detector sends a pulse indicating a car is ready to enter...
micro stepper
In a traditional microstepping motor controller, multiple parallel outputs from a microcontroller are utilized, which are then converted to analog signals using a Digital-to-Analog Converter (DAC) and sent through a power amplifier to drive the motor coils. This method is...
Big Trak Motor Driver Schematic
Schematic of Big Trak's motor driver circuit. The toy includes 9112 and 9113 transistors (and sometimes 2N6715) because the 75494 chip cannot supply enough current to run the Big Trak's motors by itself.
The motor driver circuit for the Big Trak...
Stepper Motor circuits
A stepper motor is a motor controlled by a series of electromagnetic coils. The center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately energized or de-energized, creating magnetic fields that either...
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...
circuit explanation of stepper motor
A Darlington connection-type transistor is utilized for driving the coil. In this configuration, two stages of transistors are connected in series, resulting in a high current gain, where the "hfe" of the Darlington transistor is the product of the "hfe"...
