Electrical Workshop

Before you start soldering a small DC circuit, you can check what the numbers are going to do. Set the supply voltage, build the circuit on a visual sheet, and watch the main instrument report total current together with the share of the wire's allowed load. The scale changes color as the limit gets closer. The workbench also shows voltage headroom, resistance, and power. Open Parts and details to add resistors, LEDs, loads, and cable between the supply rails. The app flags an open circuit, missing resistance, LEDs using all available voltage, or parallel LEDs without individual current limiting. Four calculators cover common checks. The voltage divider tool reports output voltage, current, and power on each side. The LED resistor calculator gives the ideal resistance, nearest E12 value, power, and current. Color code decoding uses four selectable bands to return resistance and tolerance. Cable drop shows loop resistance, voltage loss in volts and percent, remaining voltage at the load, and allowed current for the selected cross-section. All inputs opens the complete form, and any result can be written to the journal. Projects keeps saved circuits. The one currently on the workbench appears first with its saved status; other entries can be opened, duplicated, or deleted. New circuits use the default voltage and wire cross-section from your profile. Journal stores calculation history by type, with filters for circuits, dividers, LEDs, color codes, and cables. You can delete records one by one or clear the history with confirmation. Settings holds your profile with name, role, and photo from camera or gallery; initials appear until a photo is added. You can set defaults for new circuits, toggle haptic feedback, replay the introduction, view stored-data counters, and remove history or projects with confirmation. Everything works offline, with no registration or internet connection required. Saved data stays on the device.
