Remote control robot circuit
The remote control robot circuit is illustrated in the accompanying figure. Figure 2-36(a) presents the circuit diagram, while figure 2-36(b) depicts the operating timing diagram. The robot's rotation process involves an ultrasonic launching circuit, which consists of a 40 kHz...
Wifi Robot
A remote control car can be operated over the internet or wirelessly from a laptop up to 500 meters away. It features a live-feed network camera for driving without line of sight and a horn for signaling. The project utilizes...
Pulse Width Modulation DC Motor Control
Often, people attempt to control DC motors with a variable resistor or variable resistor connected to a transistor. While the latter approach works well, it generates heat and hence wastes power. This simple pulse width modulation DC motor control eliminates...
200 meters remote control schematic design
Early transmitters using LC oscillators experience significant frequency drift. The introduction of Surface Acoustic Wave (SAW) devices addresses this issue, providing substantial frequency stability comparable to crystals. These devices can achieve fundamental frequencies in the hundreds of megahertz or even...
RC Servo Processor
In the ongoing development of an autonomous sailing robot, a method was required to expedite the prototyping of boat designs. The objective was to utilize a standard remote control (RC) model control system to leverage off-the-shelf components, thereby saving time....
PWM Speed Rotation Forard-Reverse and Regenerative Braking
This circuit is a PWM speed control circuit for a DC motor rotation. It supports forward and reverse rotation as well as regenerative braking functions. The circuit utilizes a PWM signal to control the speed of a 12V DC motor...
Pwm motor speed control
Speed control is achieved through pulse width modulation (PWM) of the gates of two MGP20N45 TMOS devices. Consequently, the motor speed is directly proportional to the pulse width of the incoming digital signal, which can be generated by a microprocessor...
remote control mains switch
As the only electronics engineer in the family and circle of friends, it is sometimes challenging to decline requests for assistance. Recently, a friendly elderly lady in a retirement home sought help regarding her lighting situation. In her room, the...
Inexpensive Remote Watering System
This remotely controlled watering system is cost-effective and easily expandable. It operates in conjunction with a conventional watering timer, enabling remote switching between nine zones. The prototype is designed for use with a bore system, where a deep-well pump must...
