Sound-To-Servo Driver

This page outlines a project that utilizes an audio signal to control an RC servo. The movement of the servo is proportional to the loudness of the sound. This concept is particularly applicable for creating animated mouths for talking and...

Motor Speed Control Using PWM

Pulse width modulation, commonly referred to as PWM, is utilized to regulate the power supplied to a load without sacrificing efficiency. This technique is often employed in controlling the speed of an electric motor. PWM operates by varying the width of...

Gray Projects

After learning to operate the device, it became evident that inertia posed a significant challenge. The constructed system is notably heavy, making it difficult to initiate motor operation at full speed. Despite having some understanding of physics, practical experience is...

2 -Y- connection automatic three-speed motor acceleration control circuit

Figure 3-118 illustrates an automatic acceleration control circuit. This circuit employs a male contactor time relay, enabling the motor to start automatically at a low speed before transitioning to high-speed operation. The automatic acceleration control circuit depicted in Figure 3-118 is...

Exploring Microcontrollers

Many of today's appliances feature displays and buttons. Instead of relying on motors and gears, numerous household items now incorporate embedded microcontrollers. This exploration focuses on how to experiment with microcontrollers at home. Microcontrollers serve as the central processing units for...

Hobby-Servo Encoder Retrofit

The encoder strip should be laser-printed on sticky label material. It is then cut out and wrapped around the barrel of the second drive gear. Bright white sticky address labels, such as Avery "WeatherProof White Labels" #15510, are recommended. The...
