microcontroller Generate a reset signal from a falling edge trigger
The microcontroller design features the microcontroller (MCU) in hibernation mode, which can only be awakened by a pulse (high-low-high) signal on the reset pin (active low). An accelerometer or an external real-time clock (RTC) serves as the wake-up source. The...
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....
servo motor control with microcontroller
The shaft can be positioned at specific angular positions by sending a coded signal to the servo. As long as the coded signal is present on the input line, the servo will maintain the angular position of the shaft. Changes...
Microcontroller Programming 2
For this week's assignment, a chip design was provided, and the task was to incorporate a button and an LED (light-emitting diode). The objective was to fabricate the chip and program it to interact with the light and button. Given...
Servo motor speed control circuit
The servo motor speed control circuit connects the photoelectric encoder to the motor shaft. The LED serves as an indicator light for the phase-locked loop (PLL) detection, illuminating when the control circuit is synchronized. The PLL employs a phase synchronous...
servo circuit
Servo motors are utilized in various applications, including robotics, puppetry, photography, and more. These compact motors can adjust their output shaft to a specified position on command and maintain that position. Most servos offer a range of motion of approximately...
servo timer
The Servo Timer II was primarily designed for parachute deployment on water rockets but can be used for other applications. The timer controls a single RC servo motor that can open a latch on a parachute door. Once triggered, the...
Motion Control Sensor Interface
The task involved implementing and programming all hardware devices to make data accessible to the receiver program running on a PC. This included configuring all Prospeckz devices and establishing protocols for radio transmission communication back to the PC. Additionally, the...
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...
