Hobby Robotics 7 circuit | Next Electronics

Power three force-sensitive resistors (FSRs) or any other analog sensor with 5V in parallel. Connect each sensor to analog pins 0-2, utilizing a 10K resistor as a reference to ground on each input line. The provided sketch reads three analog...

The Cylonduino Arduino Experiement

A significant amount of extra hours has been dedicated to work in anticipation of an editing deadline. Despite this, it is deemed appropriate to attempt some hardware hacking. An interest in electronics has existed since before the advent of computers,...

audio Using a microphone with an Arduino

This project requires expensive hardware, including a microphone and amplifier, along with sophisticated audio analysis on the microcontroller. Even a complete microphone with an amplifier circuit does not yield the desired results, as noted in the product comments. The individual...

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...

Arduino AVR High-Voltage Serial Programmer

This Arduino sketch is designed to recover ATtiny microcontrollers that have become non-functional due to incorrect fuse settings. It achieves this by placing the affected ATtiny into high-voltage serial programming mode and rewriting the fuses to safe values. The Arduino...

Ardurino Logger

The switches and LEDs are mounted on the same front panel as the display, while the "D" connector is located at the rear. The two switches are momentary switches that activate downwards but latch upwards. Assorted components, such as single...

Worlds Smallest Stepper Motor with Arduino and EasyDriver

A video and the circuit with schematics for connecting and controlling the world's smallest linear actuator based on a bipolar stepper motor from a Blu-ray drive. The project involves the design and implementation of a circuit to control a linear actuator,...

Remote-controlled fiber-optic Ceiling Light with Arduino

A wooden table features numerous holes of varying diameters designed to accommodate optical fibers. Due to the size of the ceiling lamp (90 cm x 60 cm), it was not feasible to utilize a single bundle of fibers, resulting in...

Load Cell with an Arduino

A system has been developed that employs eight air-clamping cylinders (McMaster-Carr 62185K64) to apply pressure on a glass piece, sealing it to a sidewall. However, the glass has cracked multiple times, prompting the need for a cost-effective method to measure...
