servo etc.

3.3 Volts to 5 Volts the easy way.

It doesn't get more simple than this...

The above circuit worked to let a 5 Volt servo work on a 3.3 Volt signal. This DOES NOT convert power so connect the servo power connections to 5 Volts and ground. This only converts the low power signals (before this my servo wouldn't move!)

Now, the resistor is 1000 ohms or 1 K (brown, black, red). Wattage isn't citical. The diodes are 1N914 or 1N4148 any good silicon (Switching) diode should work.
