Overview of Servo Motor A servo motor is an electrically powered actuator that allows for precise control of angular rotation. It provides controlled movement important for applications like robotic arms that require precision. The rotation angle is dictated by a PWM (pulse-width modulation) signal sent to the motor. Varying the width of the PWM pulses […]

Abstract This Internet of Things (IoT) project utilizes speech recognition to display announcements on a light-emitting diode (LED) matrix notice board. By leveraging Google Assistant’s speech-to-text capabilities, notices can be verbally dictated rather than manually typed, saving time and reducing the risk of unauthorized modifications. The proposed system is built around an Arduino microcontroller and

The ATMega32 is an widely used microcontroller from Atmel. It shares many similarities with the ATMega328P but has a more reduced memory capacity. However, the ATMega32 makes up for this with a greater number of input/output pins available. A key advantage of the ATMega32 is that each GPIO pin can exclusively support either digital input/output

7-segment displays comprise 8 LED elements – 7 linear segments that form numerals, plus a circular dot. Numbers 0-9 and some letters (A, C, D, E, F, H, L, O, P, U) are represented using combinations of the 7 lines. The dot creates decimals. Each element connects to a dedicated pin, allowing individual control. Pins
