When the input is "0" the voltage is 190mV. When the input is "1" the voltage is 5v. |
| rstofer:
That seems about right. VCESat for most transistors is about 0.2V so 190 mV is pretty close. The transistor is saturated - it is fully ON. The 5V reading is also about right. There's very little current flow through the resistor so there is very little voltage drop. Glad it works! |
