Emergency Pump Control with 555

The 3D printer necessitates independent control for three separate axes. Each controlled axis must be equipped with a high-precision electronic driver. The mechanical components of each axis utilize a precise bipolar stepper motor connected to a drive shaft via...

The LED running light project can be easily implemented using microcontrollers, particularly the Microchip PIC microcontroller. This project utilizes the PIC16F877A microcontroller, which features a 40-pin IC configuration, with LEDs connected to port B. The LEDs twinkle in accordance...

The LS-2 remote control switch infrared sensor module is similar to the LS-18 but functions as a reflector. The LS-2 pin diagram and internal block diagram provide insights into its electrical parameters. The operating voltage for the LS-2 remote...

The 51 microcontroller features a full-duplex serial communication port, enabling straightforward serial communication between the microcontroller and a computer. However, certain conditions must be met for effective communication, such as the computer's serial port operating at RS232 levels while...

For a project, there is a need to display a progress bar representing the activity performed by a microcontroller unit (MCU). A bar graph display is intended for this purpose; however, the bar graph display driver IC, LM3914, requires...

The medical ventilator controller circuit consists of an astable oscillator, a control circuit, and a power supply circuit. The astable oscillator is constructed using resistors R1, R2, a potentiometer RP, capacitors C1, C2, and a time base integrated circuit...
