A **programmable power supply** is an electronic device that provides controlled and adjustable electrical power to a circuit or device. Unlike fixed power supplies, it allows users to set voltage, current, and sometimes power limits through software, digital interfaces, or manual controls. These power supplies are commonly used in testing, automation, and research applications where precise and repeatable power control is required. They often feature remote programmability via USB, Ethernet, or GPIB interfaces, making them ideal for integration into automated test setups.
This ESP32 smartwatch PCB is a compact, wearable design featuring Wi-Fi, Bluetooth, an OLED/TFT display, and essential sensors like an accelerometer and heart rate monitor. It includes Li-Po battery management, optimized power efficiency, and a sleek layout for smart wearable applications.
RFID-based toll collection systems use Radio Frequency Identification to automate vehicle toll payments. Each vehicle is equipped with an RFID tag containing user and payment information. As the vehicle passes through the toll gate, an RFID reader scans the tag and deducts the toll fee. This system reduces congestion, minimizes human error, and speeds up toll transactions.
A Smart Bicycle Lighting System enhances cyclist safety with automatic headlights and taillights that adjust based on ambient light. It includes a brake light function that activates during deceleration and turn signals for better road communication. Some versions feature wireless control via Bluetooth, allowing customization through a smartphone app. Designed using KiCad, it integrates microcontrollers, sensors, and power management for efficient and reliable performance.
A Solar Tracking System is designed to maximize solar energy absorption by adjusting the position of solar panels based on sunlight direction. This project uses a custom PCB integrating sensors, a microcontroller, motor drivers, and power circuits to automate the tracking process.
This is the pcb designing for gsm based home security system.
The project is about creating a pcb for buck and boost converter.
