NPN transistors use the format of EBC which stands for Emitter Base Collector.
PNP transistors use the format of ECB which stands for Emitter Collector Base.
Step 1: Materials
- LED of any color
- 9 volt battery
- bendable material to make the case
- 3-4 pin socket for transistor
- 10k ohm resistor
- 470 ohm resistor
- NPN transistors
- Small Switch
Step 2: Testing
Step 3: Construction
The transistor circuit I found was used as a way to learn transistors I just modified the circuit by allowing the transistor to be removable therefore leading to the circuit now becoming a transistor tester.
Step 4: Casing

Okay at this point I hot melt the circuit components in to pre-cut openings and I was constantly checking the connections to make sure everything was in order by having the transistor in the place lighting up the LED the whole the time. You would hate for a fault in the wiring after you closed everything back up with hot melt.
Step 5: YAY Finish
