CircuitBuddy helps you when you're building circuits! Simply ask it what resistor to use for a certain value and CircuitBuddy will answer with the color code for the resistor. Conversely, tell CircuitBuddy the color bands of a resistor and it will tell you its resistance. You can also ask about capacitor codes to determine the value of a capacitor or ask about a capacitance to get the corresponding code.
CircuitBuddy is still being actively developed and will support more questions soon! Want to contribute? CircuitBuddy is open-source and can be found at https://github.com/benwiebe/CircuitBuddy .
“Alexa, ask CircuitBuddy what is a red green blue gold resistor.”
