Bipolar Stepper Motor H-bridge circuit

An analog output for Arduino can be achieved using a Digital-to-Analog Converter (DAC), commonly implemented with an R-2R ladder circuit. However, this DAC lacks an output buffer, which would enhance reliability and compatibility with various loads. For optimal performance, incorporating...

PWM DC Motor Speed Control

This is a circuit for controlling the speed of small DC motors; it works nicely as a speed controller for an HO or N gauge model railroad. More: The left half of the 556 dual timer IC is used as...

Arduino Producing DTMF Tones

The project involves teaching an Arduino to generate DTMF (Dual-Tone Multi-Frequency) tones using the HT9000A DTMF chip. These tones are the familiar "touch tones" used in telephone systems. The output volume from the chip is low, suggesting the need for...

Arduino Retro Computer with SD card and LCD

A BASIC preprocessor has been developed using Python, enabling code writing without line numbers and allowing the use of labels. This preprocessor automatically assigns line numbers to the code and converts labels accordingly. An example of its application is demonstrated...

Blinken lights circuit

Arduino consists of two main components: the hardware (the Arduino board) and the software (the IDE). The advantage of using Arduino is that circuits can be built and their behavior modified by altering the code instead of changing the hardware....

learning Arduino programming

The circuit consists of a 10 kΩ resistor, a 470 kΩ resistor, a potentiometer, and an LED. This circuit is intended for learning Arduino programming in class. The circuit utilizes a combination of resistors and an LED to create a...

CSC231 Homework

A diagram is requested to illustrate all hardware components used in a project and their connections. The diagram should depict the Arduino board as a box with lines indicating connections, arrows showing signal direction (inputs or outputs), and pin numbers....

Motor Generator Stepper

Stepper motors are a frequently discussed topic. This circuit converts a clock signal from a square wave generator into signals that have a 90-degree phase difference, which are necessary for driving the stepper motor windings. The trade-off for this simplicity...

H-bridge of 40N60 mini-brick IGBTs

This first DRSSTC evolved from the ISSTC work previously undertaken. After discussions with Jimmy Hynes, the creator of the first DRSSTC, it was decided to implement a modified design. Hynes' DRSSTC utilized an oscillator to produce a high-frequency signal for...
