The very popular 595 shift register chip of the 74 series is used a lot by hobbyis because of its wide availability, good speed and simplicity. Just plug it on an arduino like shown in the tutorials and youi have 8 more outputs, put two and you have 16 more outputs ! (up to a lot of them actually, with only three pins !)
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package.
This protoboard is double sided, meaning that you can easily put components on both sides. It is perfect for all your DIY projects, as with its 0.1" (2.54mm) pitch it fits nearly all the through hole components.
This is a power module for the standard bread boards (Small and Medium sized). It's concave design so will not wast your proto zone. It also supports both 5v and 3.3v (both can be enabled on each power rail).
We think it is a must to have on your workbench, really.
Un encodeur vertical pour vos projets: c'est comme un potentiomètre mais sans fin. Il envoie des pulses à votre micro controlleur pour vous signaler les directions de rotation. Ce type d'encodeur est beaucoup utilisé en HIFI.
Simple micro switch that can be used as a limit switch, as a drawer switch or whatever you'd like. It even support higher current loads, so you can switch motors or high power leds with it (hint hint).
