3ch Rremote
When the detect subroutine is invoked, it initially waits for a start bit. The duration of the low segment of the first start bit is measured. If the low pulse of the first start bit exceeds 1.020 ms or is...
EM4294 13.56MHz Crypto Analogue Front End Circuit For High Secure RFID Communication
The EUA2032 is a high-efficiency, 2.5W mono class-D audio power amplifier. A newly developed filterless PWM modulation architecture further reduces EMI and THD+N, as well as eliminates the LC output filter, thereby reducing the external component count, system cost, and...
Atari Joystick Wired Remote Control for Robots
The simplest solution for implementing joystick control for a robot is to program the actions in software on a microcontroller. However, many users prefer off-the-shelf components, thus this circuit is designed using diodes, resistors, transistors, and a FAN8200 motor driver...
Pulse Operation of DC Solenoids
The solenoid operates with pulse action, receiving a brief surge of five to six times its rated voltage, followed by a holding voltage that is less than half of its rated voltage. This method significantly reduces application time, and the...
Inexpensive Remote Watering System
This remotely controlled watering system is both inexpensive and easy to expand. It is designed to operate in conjunction with a conventional watering timer.
The remotely controlled watering system is an innovative solution for automated irrigation, allowing users to manage watering...
Baseball
The objective of this project was to create an interactive baseball game inspired by pinball mechanics. The game features a solenoid-powered bat and a pitching mechanism that employs a motor and lever arm arrangement. Both components are controlled by buttons,...
remote
Each unit features four channels, enabling the programming and operation of up to four separate devices with a single remote, provided these devices operate on the same frequency. The unit can automatically learn from existing garage door remotes or built-in...
A simple remote control switch circuit
The ML4423 is an integrated controller designed for single-phase and two-phase AC induction motors. It features PWM (Pulse Width Modulation) capabilities for speed control and includes various protection circuits such as short circuit protection, fire protection, and a reference power...
Baseband Circuits for an RFID Receiver
Figure 1 shows the block diagram of a direct conversion RF receiver—the receiver demodulates an RF carrier directly into a baseband signal without an intermediate frequency down-conversion (a zero IF receiver). The antenna, shared by both the transmitter and receiver,...
