You'll find these rotary potentiometers in our Maker Essentials kit, but they're so useful we decided to offer them on their own! Pair them with something like our Explorer HAT Pro or Explorer pHAT to read precise values from them. Total resistance: 1kΩ, 10kΩ or 100kΩ Total resistan...

SKU: SF-COM-14622

An adjustable potentiometer can open up many interesting user interfaces. With this rotary potentiometer just turn the dial and the resistance changes. This potentiometer has a ¼" metal knurled shaft diameter, solder lug terminals, no detents, and has a 100K linear taper. Connect VCC to an outer...

SKU: SF-COM-14624

A panel-mount rotary potentiometer with a 100 kΩ logarithmic taper. Turn the knob and the resistance changes smoothly — ideal for volume controls and other audio applications where a logarithmic response matches human perception. Connect VCC to one outer pin, GND to the other, and the centre pin...

The Adafruit PN532 NFC/RFID Controller Shield brings 13.56 MHz NFC and RFID capabilities to your Arduino. Built around the PN532 chipset — the most widely used NFC controller, found in virtually every NFC-enabled phone and device — it can read and write to NFC/RFID tags and cards of Type 1 throug...

SKU: SF-COM-09939

An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC...

SKU: AF-642 · MPN: 642

This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable. Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be...

Measuring stretch forces isn't easy - unless you have some conductive rubber cord! This cord is 2mm diameter, and 1 meter long, made of carbon-black impregnated rubber. Usually this material is used for EMF gasketing, but its also very fun to play with.In a 'relaxed' state, the resistance is abou...

This 20×4 character LCD features black text on a full-colour RGB backlight that you can set to any colour — red, green, blue, purple, teal, white, and everything in between. It's the most daylight-readable character LCD available and looks strikingly good at any colour or brightness level. A dro...

SKU: AF-498 · MPN: 498

This is a fancy upgrade to standard 20x4 LCDs, instead of just having blue and white, or red and black, this LCD has full color RGB characters on a dark/black background! That means you can change the character display colors to anything you want - red, green, blue, pink, white, purple yellow, te...

SKU: AF-464 · MPN: 464

The eTape Liquid Level Sensor is a solid-state resistive sensor that measures fluid level without mechanical floats. As the liquid level rises, the hydrostatic pressure compresses the sensor envelope, decreasing its resistance. The output is inversely proportional to the liquid height — lower liq...

This is a fancy upgrade to standard 16x2 LCDs, instead of just having blue and white, or red and black, this LCD has full color RGB characters on a dark/black background! That means you can change the character display colors to anything you want - red, green, blue, pink, white, purple yellow,...

SKU: AF-398 · MPN: 398

A 16 × 2 character LCD with a full RGB backlight, displaying black text on a customisable colour background. Set the backlight to any colour — red, green, blue, purple, teal, white, or anything in between — by controlling three independent LED channels. With excellent daylight readability and vib...

SKU: AF-386 · MPN: 386

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing t...

SKU: AF-381 · MPN: 381

This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get an...

SKU: AF-374 · MPN: 374

These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the s...
