This is an eight-way signal remote control selection circuit composed of ZHJ-9904. It includes a remote control transmitter circuit, an eight-way switch control circuit, and a remote control transmitter.
The eight-way signal remote control selection circuit utilizing the ZHJ-9904 is designed...
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...
Microcontroller based College Automation System
This project is a microcontroller-based college automation system aimed at addressing the challenges faced in educational institutions. It replaces the conventional notice board with an automated device that allows users to both hear and read the information being announced through...
REMOTE CONTROL ANALYZER
A schematic diagram for the remote analyzer is presented. The circuit operates from a basic 5-V power supply, which includes components PL1, S1, T1, a bridge rectifier made up of diodes D1 through D4, capacitor C1, and a common 5-V...
using microcontrollers
This schematic illustrates the placement of a decoupling capacitor on the right side, which should be positioned as close as possible to the power pins of the microcontroller. It includes a crystal oscillator, which is optional; an internal RC oscillator...
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...
Jet
The microcontroller is able to make about 7000 complete line-following decisions per second, which is almost 7 decisions per millimeter when the robot is going full speed. By upping the clock, unrolling loops, and removing my wireless debugging and extraneous...
Remote-Control Analyzer Circuit
A schematic diagram for the remote analyzer is presented. The circuit is powered by a simple 5-V supply, which includes components such as PL1, SI, Tl, a bridge rectifier formed by diodes D1 through D4, capacitor CI, and a standard...
