When you need to switch a lot of power, N channel MOSFETs are best for the job. These FETs can switch over 60A and 30V and are TO-220 package so they fit nicely into any breadboard or perfboard. Heat sinking is easy with TO-220's, but because of the very low Rds(on) of down to 0.009 ohms (depending on the Vgs - check the datasheet) you can get away with no heatsinking for pretty high loads! The threshhold voltage is also very low, less than 2.5V...

Add another 16 pins to your microcontroller using a MCP23017 port expander. The MCP23017 uses two i2c pins (these can be shared with other i2c devices), and in exchange gives you 16 general purpose pins. You can set each of 16 pins to be input, output, or input with a pullup. There's even the ability to get an interrupt via an external pin when any of the inputs change so you don't have to keep polling the chip. Use this chip from...

OK, this item is pretty simple - it's a panel mount pushbutton. It's not that exciting, no LEDs, no bells & whistles. But we really like it anyways – look at that lovely rounded shape, that elegant bevel. If you're going to go with a momentary pushbutton, let it be this one! The button is a normally-open micro-switch. When pressed, the contacts short closed and Bob's your uncle!

Push once to turn on, push again to turn off! This clicky switch makes a great power switch or mode toggler. We like this switch because it's breadboard friendly and more fun than a power switch. Can reliably handle up to 500mA and up to 50V. This is a really satisfying switch. The leads are not on a perfect 0.1" grid so for use with a breadboard just bend the leads out just a tad and snap into a solderless breadboard or perfboard.

This potentiometer is a two-in-one, good in a breadboard or with a panel. It's a fairly standard linear taper 100K ohm potentiometer, with a grippy shaft. It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a breadboard or perfboard. Once you're done prototyping, you can drill a hole into your project box and mount...

Micro-switches are often found in arcade buttons and joysticks but they're also really handy in any kind of mechatronics project or when you need a basic sensor. They are always 'tactile' (clicky feeling), and 'momentary' (the switch closes when pressed, then snaps open once released). They come in a few different varieties (mostly having to do with the contacts and how big the actuator is). This microswitch has a flat metal...

Turn any surface/wall/table etc into a speaker with a surface transducer. This type of speaker does not have a moving cone like most speakers you've seen. Instead, a small metal rod is wrapped with the voice coil. When current is pulsed through the coil, the magnetic field causes a piece of metal to expand and contract - and if it's pressed against a surface it turns the transducer into a speaker! Often these size transducers are pressed...

Turn any surface/wall/table etc into a speaker with a surface transducer. This type of speaker does not have a moving cone like most speakers you've seen. Instead, a metal rod is wrapped with the voice coil. When current is pulsed through the coil, the magnetic field causes a piece of metal to expand and contract - and if it's pressed against a surface it turns the transducer into a speaker! Often these size transducers are pressed up...

In this world nothing can be said to be certain, except we need headers, headers, and more headers! Each pack contains five 36-pin short female headers, 0.1" pitch. These headers are very short for fitting into tight spaces with a height of just 5mm instead of the 'standard' 8mm. Female headers are like the duct tape of electronics. They're great for connecting things together, soldering to perf-boards, sockets for...

If you want to do more with the BBC micro:bit, getting those pins from the card-edge connector is going to be your first hurdle. Unlike many dev-boards, the micro:bit isn't breadboard-friendly. That makes the 'bit durable and easy to manufacture but means you need a special connector. This surface-mount edge connector is very slim and fully SMT, so it's a breeze to automate. It also only has contacts on one side, just like the...

This potentiometer is a two-in-one: it's a log taper 10K ohm potentiometer , with a grippy shaft an d it comes with an on-off switch . It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a perfboard. Note the spacing on the switch/pot pins is 0.2" so it wont work in a solderless breadboard as nicely, unless you...

Keep it cool with a Peltier module. These unique electronic components can generate a temperature differential when powered. That is to say, apply 5V to the red (positive) and black (negative) wires and one side will get cold while the other side gets hot. For best results, you'll need to wick away that heat (otherwise the cold side will slowly get warmer). A fan and/or heatsink is ideal. This module is a 5V module, and is rated for 5W max...

When you need to switch a lot of power, P channel MOSFETs are best for the job. These P-FETs can switch over 60V and 25A (with proper heat-sinking) and are TO-220 package so they fit nicely into any breadboard or perfboard. Heat sinking is easy with TO-220s, but because of the very low Rds(on) of down to 70 mOhms (depending on the Vgs - check the datasheet) you can get away with no heatsinking for pretty high loads! The threshhold voltage is up...
