Interactive tools: resistor calculators, a resistor for an LED, capacitors and a character generator for LCD and LED matrices.
- Resistors Resistor colour code calculator: enter a value in ohms to see its colour bands, with an explanation of how to read resistors with 4 and 5 bands.
- Resistors in series Resistors in series calculator: enter the resistor values to get the total resistance when they are connected one after another.
- Resistors in parallel Resistors in parallel calculator: enter the resistor values to get the total resistance when they are connected side by side.
- Resistor for an LED Calculator for the resistor that limits the current through an LED
- Capacitors Capacitor code calculator: enter a three-digit code (e.g. 104) to get the value in pF, nF and µF, with a table of common codes.
- Capacitors in series Capacitors in series calculator: enter the capacitor values to get the total capacitance when they are connected one after another.
- Capacitors in parallel Capacitors in parallel calculator: enter the capacitor values to get the total capacitance when they are connected side by side.
- Character generator Character generator for LCD displays and LED matrices: draw your own character dot by dot and get a byte array for Arduino (C++).
