LED current-limiting-resistor maths as an API, computed locally and deterministically. The resistor endpoint sizes the series resistor for a single LED, R = (V_supply − V_forward) / I, and returns the resistor power dissipation (I²·R), the LED power, a recommended resistor wattage rating and the nearest E12 standard value (rounded up so the LED current stays at or below the target). The series endpoint sizes the one shared resistor for several LEDs wired in series, where the forward voltages add, R = (V_supply − n·V_f) / I, and flags when the supply is too low for the string. The parallel endpoint gives the per-LED resistor for LEDs in parallel (each needs its own) and the total current the supply must deliver. Currents are entered in milliamps. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, maker, Arduino and hardware app developers, LED and lighting-circuit design tools, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is LED resistor sizing; for general Ohm's law and reactance use an Ohm's-law API and for AWG wire properties use a wire-gauge API.

Voltage Divider API
Resistive voltage-divider circuit design as an API, computed locally and deterministically. The divide endpoint takes an input voltage and two resistors and returns the output voltage Vout = Vin·R2/(R1+R2), the current I = Vin/(R1+R2) that flows through the chain, and the power dissipated in each resistor and in total — a 12 V source with R1 = 1 kΩ and R2 = 2 kΩ gives 8 V at 4 mA. The loaded endpoint adds a load resistor across R2, computes the parallel combination R2′ = R2·RL/(R2+RL) and the loaded output Vout = Vin·R2′/(R1+R2′), and reports the droop in volts and percent against the unloaded value, the classic mistake when a divider feeds a real load. The resistor endpoint sizes the missing resistor for a target output — R2 = R1·Vout/(Vin−Vout) or R1 = R2·(Vin−Vout)/Vout — so you can pick parts for a reference or sensor-bias point. All quantities are volts, ohms, amps and watts. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, embedded, hardware, sensor-interfacing and EE-education app developers, reference-voltage and bias-network tools, and maker software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is the resistive divider; for a single Ohm’s-law relationship use an Ohm’s-law API and for RC/RL filters an RC-filter API.

Resistor Color Code API
Read and write resistor colour codes and snap values to the standard E-series. The decode endpoint takes the colour bands of a 3-, 4-, 5- or 6-band resistor and returns the resistance in ohms (nicely formatted as Ω/kΩ/MΩ/GΩ), the significant digits and multiplier, the tolerance, the minimum and maximum resistance that tolerance implies, and — for 6-band parts — the temperature coefficient in ppm/K. The encode endpoint goes the other way: give it a resistance in ohms (and optionally a band count and tolerance) and it returns the colour bands, picking the nearest value representable with the available significant digits. The eseries endpoint snaps any value to the nearest preferred resistor value in the E6, E12, E24, E48 or E96 series and reports the percentage error and the neighbouring preferred values. It uses the standard IEC 60062 colour assignments (including gold ×0.1 and silver ×0.01 multipliers and the implicit ±20% of a 3-band part). Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics design, PCB and BOM work, lab and hobby bench use, repair and reverse-engineering, and teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is for resistor colour codes; for general number formatting use a number-format API.

RTD Pt100 Sensor API
RTD (Widerstands-Temperatur-Detektor) Sensor-Mathematik als API, lokal und deterministisch mit der IEC 60751 Callendar-Van Dusen Gleichung berechnet – die Widerstands-, Temperatur- und Toleranzzahlen, die ein Instrumentierungs- oder Steuerungsingenieur von einem Pt100 oder Pt1000 abliest. Der Widerstands-Endpunkt gibt den Sensorwiderstand aus der Temperatur: über 0 °C, R = R₀·(1 + A·T + B·T²) mit A = 3,9083×10⁻³ und B = −5,775×10⁻⁷; unter 0 °C fügt ein dritter Term C·(T−100)·T³ hinzu – ein Standard-Pt100 (100 Ω bei 0 °C) zeigt 138,51 Ω bei 100 °C und 80,31 Ω bei −50 °C, und ein Pt1000 ist das Zehnfache. Der Temperatur-Endpunkt kehrt dies um, um einen gemessenen Widerstand wieder in Temperatur umzuwandeln – analytisch über 0 °C, iterativ darunter – genau das, was ein Messumformer mit der Brückenablesung macht, und eine Erinnerung daran, dass eine 3- oder 4-Leiter-Verbindung den Leitungswiderstand aufhebt, sodass er nicht als zusätzliche Grad gelesen wird. Der Toleranz-Endpunkt gibt die IEC 60751 Genauigkeitsband in °C und Ω nach Klasse an – AA ±(0,10 + 0,0017·|T|), A ±(0,15 + 0,002·|T|), B ±(0,30 + 0,005·|T|), C ±(0,60 + 0,010·|T|) – der Fehler wächst mit der Entfernung von 0 °C. Alles wird lokal und deterministisch berechnet, daher ist es sofort und privat. Ideal für Instrumentierungs- und Steuerungssoftware, Datenlogger- und Messumformer-Firmware, Kalibrierungs- und industrielle IoT-Tools. Reine lokale Berechnung – kein Key, kein Drittanbieter-Dienst, sofort. 3 Compute-Endpunkte. Für NTC-Thermistoren verwenden Sie eine Thermistor-API; für Thermoelemente eine Thermoelement-API.
