10 or more switches using a microcontroller
There are several methods to read multiple switch inputs using a reduced number of microcontroller unit (MCU) pins. One approach involves using an analog MCU pin to read multiple switches by assigning a unique voltage to each switch through a...
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...
Training Boxing timer schematic
A timer is being developed for circuit training or boxing training. The timer does not require any external input, except for a reset function. The project can be simplified using a microcontroller, such as the PIC12F635, which is cost-effective at...
Electronic TIC TAC TOE
This project is not to introduce Tic Tac Toe. Everyone knows this game. It is to introduce two features: bi-coloured LEDs, microcontrollers, and the skill of writing an ALGORITHM. You can use the project to learn the skills of creating...
Interactive Voice Response System
Nowadays every institution needs automation. As a part of college automation, a project has been developed for a Voice Interactive System for College Automation. This project allows users to quickly access student attendance and marks through the telephone line without...
Electronic Projects
This program includes circuit design CAD, simulation, and auto-routing PC layout. PSPICE is also utilized at Unisys, which offers more capabilities but costs six times as much and requires annual renewal. With these requirements and others in mind, a variation...
graphical LCDs with a microcontroller
How can graphical LCDs be controlled using a microcontroller? Is there any datasheet available?
Graphical LCDs (Liquid Crystal Displays) are widely used in various electronic applications for displaying complex graphics and text. To control these displays with a microcontroller, several steps...
analog light dimmer circuit connected to microcontroller
Assistance is required to modify a light dimmer circuit connected to a PIC12C508 microcontroller. This circuit is designed for the...
The light dimmer circuit utilizing the PIC12C508 microcontroller serves to control the brightness of a light source through pulse width modulation...
Controlling high-current circuits
Digital output from a microcontroller is typically a low-amperage signal. For example, when a pin is set HIGH on the microcontroller (in Wiring/Arduino, it is digitalWrite(somePin, HIGH);), the voltage from that pin is usually +3.3V or +5V, with the current...
