Multitasking Pins
It is entirely logical that low-cost miniature microcontrollers have fewer pins than their larger counterparts, sometimes too few. Consideration has been given to how to economize on pins by making them perform multiple functions. One approach is to exploit the...
Game-scoring Display ScreenCircuit
The game-scoring display screen circuit diagram is depicted in the image above. The circuit consists of an add/subtract scoring input circuit, an add/subtract scoring circuit, a counting-decoding display circuit, and a reset circuit.
The game-scoring display circuit is designed to facilitate...
Microcontroller-based: Electric fan switching relay or triac
A project is underway to control the speed of an electric fan (220Vac, 60W, 5A max.) automatically using a microcontroller based on certain parameters.
The circuit design for controlling the speed of an electric fan involves several key components to ensure...
Exploring Microcontrollers
Many of today's appliances feature displays and buttons. Instead of relying on motors and gears, numerous household items now incorporate embedded microcontrollers. This exploration focuses on how to experiment with microcontrollers at home.
Microcontrollers serve as the central processing units for...
Low Resource Microcontroller 3 Phase BLDC Motor Speed Controller
This article discusses a minimal resource microcontroller implementation for a three-phase Brushless DC (BLDC) motor, focusing on a closed-loop speed motor controller application based on a Microchip PIC12 device. It demonstrates how minimization techniques can reduce the number of I/O...
Water Level controller
The microcontroller-based water level controller and motor protector manages the on and off states of the motor based on the water level in the overhead tank (OHT). It regulates the tank's water level through a microcontroller, thereby providing automatic protection...
Preprogrammed single-chip microcontroller
Twenty-five musical keys and 25 LEDs are provided to denote F to F" with half notes in between. Memory can store a played tune. There are ten preprogrammed tunes (each has an average of 55 notes) masked in the chip....
Industrial Building Automation System (IBAS) - 4
The two optical sensors will provide a count of individuals to the microcontroller, which will relay this value to MCU-II. The microcontroller will detect the entrance of any person through high-to-low pulse transitions on input pins A3 and A4.
The circuit...
Protecting Microcontroller Input Pins from Soft Power Switch
A soft power switch for a microcontroller is designed such that a momentary switch can activate the circuit, including the microcontroller. When the switch is pressed a second time, the microcontroller is capable of shutting itself down after executing necessary...
