Step 2: Useful Steps

❖ Steps ❖

STEP # 1 ( Connect Transistors )

► Connect 5 BC457transistors anywhere on the breadboard

STEP # 2 ( Connect wires )

► Connect wire to the base pin of one transistor to the base pin of another do this for all four transistors.

STEP # 3 ( Connect LED )

► Connect +ve pin of each LED on the +ve rail and the negative pin on the collector pin of each connected transistors.

STEP # 4 ( Connect resistors )

► Connect 1K resistor to the emitter pin of each transistor to GND

STEP # 5 ( Connect transistor )

► Connect BC547 transistor on the board

► Connect wire BTW the collector pin to the base pin of previous connected transistors

► Connect wire BTW emitter pin and GND

STEP # 6 ( Connect resistor )

► Connect 10k resistor BTW the +ve rail and the collector pin of newly connected transistor
