- ToolsResistors 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.
- ToolsResistors in series Resistors in series calculator: enter the resistor values to get the total resistance when they are connected one after another.
- ToolsResistors in parallel Resistors in parallel calculator: enter the resistor values to get the total resistance when they are connected side by side.
- ToolsResistor for an LED Calculator for the resistor that limits the current through an LED
- ToolsCapacitors 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.
- ToolsCapacitors in series Capacitors in series calculator: enter the capacitor values to get the total capacitance when they are connected one after another.
- ToolsCapacitors in parallel Capacitors in parallel calculator: enter the capacitor values to get the total capacitance when they are connected side by side.
- ToolsCharacter generator Character generator for LCD displays and LED matrices: draw your own character dot by dot and get a byte array for Arduino (C++).
