  • Arduino Leonardo R3 Board-Clone Board

    SKU: E-244 650.00 +GST
    The Leonardo is Arduino’s first development board to use one microcontroller with built-in USB. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol! It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

    Introduction: These 3-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 same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. Technical Details: Technical specs: Usable temperature range: -5° to 90°C (-23°F to 194°F) 9 to 12 bit selectable resolution Uses 1-Wire interface- requires only one digital pin for communication Unique 64 bit ID burned into chip Multiple sensors can share one pin ±0.5°C Accuracy from -10°C to 85°C Temperature-limit alarm system Query time is less than 750ms Usable with 3.0V to 5.5V power/data
  • The Keyes-039 or KY039 Heart rate monitor consists of two things, an Infrared LED, and an Infrared Phototransistor.  The IR LED should come on whenever the sensor has power and stay on (because it is infrared, you won’t be able to see that it is on, but if you look through your cell phone camera you will).  The IR photo transistor causes the voltage to change on a “sensor” wire, and this should be connected to one of the Arduino’s analog pins.
  • Pulse sensor is used to test heart rate sensors. Students, artists, athletes, creators, games or mobile terminal developers can develop heart-related and interactive works. Sensor can be worn on the finger or earlobe, It also has an open-source app program, you can put your real-time heart rate displayed by the graph. In essence, a heart rate sensor integrated optical amplifier and noise elimination circuit.

  • This is a breakout board for Freescale’s MMA7361L three-axis analog MEMS accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.
  • he 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. Introduced in 1971 by Signetics, the 555 is still in widespread use due to its ease of use, low price, and stability. It is now made by many companies in the original bipolar and also in low-power CMOS types. This module is use as a square-wave signal generator.  It generates square wave signals used for experimental development. It also generates square wave signal driving motor drive.  With adjustable pulses generated for use by the MCU and adjustable pulse control related circuits.
  • Ultraviolet rays UV Sensor ML8511

    SKU: E-261 425.00 +GST
    Description: The GY8511 breakout is an easy to use ultraviolet light sensor. The MP8511 UV (ultraviolet) Sensor works by outputing an analog signal in relation to the amount of UV light that’s detected. This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions.
    This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microcontroller can do an analog to digital signal conversion then you can detect the level of UV!
  • Arduino Pro Mini 328 Clone

    SKU: E-262 275.00 +GST
    This is  Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It’s a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage , lack of connectors, and USB off board.
