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...
Custom Arduino circuit not working
A circuit utilizes a keypad, a servo, and several LEDs, connected to an Arduino Uno. The objective was to integrate all components onto a single PCB, effectively creating a custom version of the Arduino. Upon startup, the red LED is...
Programming Arduino Wirelessly
The Arduino system provides a straightforward and open-source approach for programming microcontrollers. Typically, this involves using a serial or USB cable directly connected to the microcontroller project. However, challenges arise when the project is located in inaccessible areas, such as...
Light activated switch circuit
A simple light-activated switch circuit with a diagram and schematic using IC LM311 wired as a voltage comparator and an LDR that acts as a light sensor.
The described circuit utilizes the LM311 integrated circuit, which functions as a voltage comparator,...
Servo motor speed control circuit
The servo motor speed control circuit connects the photoelectric encoder to the motor shaft. The LED serves as an indicator light for the phase-locked loop (PLL) detection, illuminating when the control circuit is synchronized. The PLL employs a phase synchronous...
servo motor pot control
One of the motors utilized in the module is a servo motor. A servo motor is a compact motor that allows for precise positioning at various angles. It is equipped with internal circuitry that automatically maintains the specified angle. However,...
