I recently wanted some breadboard setups for students ... If you are a real minimalist, you could dump the 220 ohm resistors, too. The capacitors help decouple your power supply, but breadboards ...

The idea is to solder up some pre-made indicators with integrated resistors to save space on the breadboard when prototyping — instead of four slots, you only use two per LED. This is about as ...

(Without Microcontroller Board) Breadboard and Power Supply Modules-Include various LEDs, resistors, buttons, capacitors, a few transistors and diodes etc. With jumper wire and Male-female dupont ...
