Make your own health and fitness monitoring project with this heart rate monitor sensor kit. The compact board measures the electrical activity of the heart via three ECG electrode sensors, then filters and amplifies the analogue signals so that the...
This air quality sensor can detect a wide range of volatile organic compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. It also features a 10K precision 1% NTC thermistor, which can be used to measure the specific...
Use this air quality sensor to detect the amount of dust in the air. The small board has a SHARP GP2Y1014AU optical sensor onboard that uses an infrared LED and photoelectric transistor to detect reflected light from dust in the air. Fine particles as...
This kit uses a 4017 integrated circuit (IC), making the traffic lights flash just like real traffic lights. You can also adjust the delay between lights. Kit includes circuit board, 9 x LEDs, resistors, trimpot, transistors, capacitors, diodes, 4017 IC...
This fun retro project is based on the ATMEGA32U4 chip, driven by an Arduino Leonardo, and features a 1.3 inch OLED screen and volume control. It can be powered by connecting a USB cable or from 2 x AAA batteries (sold separately).Components:1 x Console...
This audio module can play MP3 files from installed microSD (sold separately). A built-in amplifier can power an 8-ohm speaker, and a 3.5mm audio socket is also provided for private listening using your headphones or connection to an external amplifier...
This screen uses very little power to refresh, and retains the last displayed content for a very long time when power is removed. The screen also reflects ambient light, which avoids the need for a backlight, and makes it easy to read under bright...
This display features 128 bright blue LEDs arranged in an 8 x 16 grid, brightness control, and communicates to your microcontroller via I2C. It can be powered from 3.3V or 5V, and connects to your controller board using the supplied 220mm long 4 pin...

Onboard ambient light, RGB colour, and proximity sensors detect the hand movements in six different directions, then sends the data to your microcontroller over standard I2C communications. It has a detection range between 100 - 200mm, and uses UV and IR...
This sensor module works like an adjustable resistor that changes based on pressure on the centre pad. It converts pressure signal from the sensor into an electrical signal output with a corresponding change in intensity to differing force. Easy to...
Rotary encoders are classified into two types: absolute and incremental. The absolute encoder reports the exact position of the knob in degrees, whereas the incremental encoder reports the number of increments the shaft has moved.While rotating this...
