This thumbstick is an analog joystick - more accurate and sensitive than just 'directional' joysticks - with a 'press in to select' button. Since it's analog(10k potentiometers), you'll need two analog reading pins on your microcontroller to determine...

Instructions for Use Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil...

This module is an analog magnetic field sensor. The strength of the field is given by an analog voltage at the signal pin of the module. The sensor must be connected to GND and 5V of the Arduino board. The output voltage is measured by analog pin A5 on...

Transparent 5mm tri-color LEDs with separate red, green and blue LED chips inside! Nice indicator, and fun to color-swirl. 60 degree viewing angle. We like diffused RGB LEDs because they color mix inside instead of appearing as 3 distinct LEDs. These...

Features: On-board MAX485 chip, A low power consumption for the RS-485 communication, slew-rate limited transceiver. On board then 5.08 (mm) pitch 2P terminal to facilitate RS-485 communication wiring. All pins of chip have been lead to can be...

This is the assembled version of the Pi T-Cobbler Plus.  It only works with the Raspberry Pi Model Zero, A+, B+, Pi 2, Pi 3 & Pi 4! (Any Pi with 2x20 connector)The Raspberry Pi B+ and Pi 2 has landed on the Maker World like a 40-GPIO...

Resistors are a good thing, in fact, they're actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you're gonna have the resistor you need when you need it is to...

Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to...

A full color RGB LED ring light! These chrome-plated metal buttons are rugged, but certainly not lacking in flair. Simply drill a 16mm hole into any material up to 1/4" thick and you can fit these in place - there's even a rubber gasket to keep...

Pimoroni has stepped up their LED game! Unicorn HAT HD crams 256 RGB LEDs, in a 16x16 matrix, onto a single HAT. High-definition rainbow goodness! You can still use it for all of the same things as the regular Unicorn HAT, but with 4 times as many...

If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope and magnetometer into actual "3D space orientation"! Orientation is a hard problem to solve. The...

Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in both I2C and...

Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can...
