Reply to "Resistor Assortment"

Stock some Cl2-N3 chips then there is no need to guess at resistor values.

For resistors,stock up to 1200 ohm for LEDs. Stock some 100 ohm,240 ohm 510 or 560 ohms,330 ohm,1k ohm. Combine values to make other resistor values if you do not have the right one. 2, 510 ohm in parallel equals 255 ohm. 2, 510 in series equals 1020 ohms. Always go equal to or over the value needed in the calculation for LEDs. If a capacitor is used on pulsed current add 1.4 times the input voltage. A little over is not critical. Use larger values to dim LEDs. Also sometimes a 1/2 watt resistor is called for so 2, equal 1/4 watt resistors in series gives you a 1/2 watt one for example at 2 times ohm value.

The LEDs I buy come with 510 ohm resistors.
