Introduction: Simple Transistor Switching
Transistors have 3 pins: Emitter, Base, and Collector. If you apply power to the Emitter and Collector pins, the Collector will emit power. This can be used to make electronic switches, passcode locks, ETC.
This uses:
- 1x 2n3904 Transistor
- 1x Switch
- 1x LED
- 1x 100R Transistor
- 1x Breadboard
- And Some Breadboard Wires
Step 1: EBC
Step 2: Add the 2n3904
Step 3: Add the Positive Wire
Step 4: Add the Switch
Step 5: Add the 100R Resistor
Step 6: Add Your LED
Step 7: Flip the Switch a Few Times?
Does the LED turn on or off?
