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...
Motor Controller
A dual DC motor controller employs an H-bridge controller chip. In addition to the standard features of the H-bridge driver chip, such as thermal and over-current protection, the circuit supports dual 12V/5V regulated power supplies, sign/magnitude and brake driver logic,...
PWM Generator
A pulse-width modulated (PWM) signal can be generated using a triangle wave and a comparator. The digital-to-analog converter (DAC) serves as the input signal, and the resulting output signal's duty cycle will be proportional to the input voltage. This PWM...
PWM Fan Controller schematic
The heart of the PWM Fan Controller is a PIC 12F675 microcontroller. This microcontroller is reading the analog output of a LM35 temperature sensor using a ADC (analog to digital converter). The resulting digital value is converted to a temperature...
Password Based Door Locking
Security is a prime concern in our day-to-day life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain. The microcontroller based Door locker is an access control...
Bi-directional motor
This is a simple and easy-to-construct circuit designed to provide a bidirectional drive for a DC motor. The circuit operates straightforwardly. The output of an astable multivibrator based on IC1 (NE555) is utilized to control the relay RL1 that drives...
clap sensor construction
The clap sensor is a straightforward circuit that consists of a PC microphone, a microcontroller, and an output. The circuit design features the ATtiny84 microcontroller, chosen for familiarity with the AVR architecture and accessibility to necessary tools. The ATtiny84 is...
working principles of motor control
After dismantling a Chinese copy of a Segway, an examination of the motor controller was conducted. After several hours of work with a multimeter, pen, paper, and KiCad, a block diagram and schematic of the motor controller were developed. This...
