The object is to provide enough power for a solenoid.

I know that the SX pin will not provide enough current for the solenoid, so I am putting in a darlington transistor in circuit to provide current from the source voltage. 

My goal was:

When the SX Pin is high, no current is flowing to the connector at the collector.
When the SX Pin is Low, the source voltage (5V) is flowing to the collector at the connector.

When I measure the voltage on the SX pin, it is correct 0 or 5V.
When I measure the voltage on pin1 of the resistor, it is correct (based on what the SX pin is saying)
When I measure the voltage on Pin2 of the resistor, or anywhere beyond the Transistor, I am reading about 2V.

I think the Transistor may be blown, and I want to replace it, but I want to make sure I have the correct resistor values/theories behind it to prevent it from blowing again.
