I used 2N2222A NPN and 20k resistor instead, it just lights up and doesnt flash, do you know what the problem can be?
@TimGrayАй бұрын
website address is completely dead. anyone put it in a place that sticks around like github? also posts below code is wrong compared to board. Wow this is really a mess. If you follow the video be sure to change the pin assignments in the code posted in comments as they are completely different.

Some may have missed this , but the Pos Red and Yellow are on the same line of the BB so a single line to + buss get both. The - end Cathode is on two separate lines. If you have one light not flashing this may be your problem. also check the wire connections from the diodes and their polarity. Long leads are +. A coin 3volt battery is a good way to verify that LED is good and give correct polarity, Do not use a 3.7 lit it will fry your diode . A schematic would be good but trouble shooting is part of electronics.

Id like to use 3.2 - 3.6 Volt Leds, is that possible with this circuit?
Why does the LED light up very brightly if I touch the base? Do I have some kind of superpower?
@henfati15476 ай бұрын
Its just the change of resistance on the transistor, kinda like a touch buttom

Please be careful when using a breadboard. It will create frequencies that will enter your body and cause damage. Wrap either the breadboard or your body in tinfoil to block out the frequencies. You must be careful with frequencies.

Unfortunately what you presented on the video and the schematic are complete different, even the components you listed on the website are not completely in the schematics
