I was trying to drive an LED with a TTL and a transistor circuit. The circuit is set up as shown in the picture. As I turn on the dc voltage, the LED is constantly on instead of pulsing like the TTL. Then I ground the TTL input and weirdly the LED is still on. This is the first time I've learned to use a transistor so I don't know what I did wrong.
p.s. the transistor is a 2N2369A and the TTL is 3V 1kHz and 100ns wide
and the LED is 20mA @ 3.8V forward voltage
Thanks
