Copper and Zinc Plate Battery Experiment Kit (DIY fruit battery)
Description

Do you know that fruits can produce electricity? When two different metals are placed in a common conducting solution which in this case, the juice inside the fruits, electricity will be produced. This is the basis of the electrochemical cell or wet cell. If you have a piece of fruit, a couple of copper and zinc plates, and some wire, then you can generate enough electricity to turn on an LED! Making a fruit battery is fun, safe, and easy.

Watch a video on this kit at https://youtu.be/gmtJWYzdPbk

Get this kit to keep your kids occupied with hands-on activities while enjoying the new knowledge while having fun! This DIY kit is simple enough to be built by 4 years old children, with parent's help. And children 6 years old and above can build it by themself! Let them explore electricity at a young age! You can also let your kids understand how an electrochemical cell or wet cell works. Awesome!

Adafruit Circuit Playground Express (Circuit playground express)

Description:

Circuit Playground Express
 is the next step towards a perfect introduction to electronics and programming. We've taken the original Circuit Playground Classic and made it even better! Not only did we pack even more sensors in, we also made it even easier to program.

Start your journey with Microsoft MakeCode block-based or Javascript programming. Or, you can follow along with code.org CS Discoveries. Then, you can use the same board to try CircuitPython, with the Python interpreter running right on the Express. As you progress, you can advance to using Arduino IDE, which has full support of all the hardware down to the low level, so you can make powerful projects.

Because you can program the same board in 3 different ways - the Express has great value and re-usability. From beginners to experts, Circuit Playground Express has something for everyone.

Here's some of the great goodies baked in to each Circuit Playground Express:

  • 10 x mini NeoPixels, each one can display any color
  • 1 x Motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)
  • 1 x Temperature sensor (thermistor)
  • 1 x Light sensor (phototransistor). Can also act as a color sensor and pulse sensor.
  • 1 x Sound sensor (MEMS microphone)
  • 1 x Mini speaker with class D amplifier (7.5mm magnetic speaker/buzzer)
  • 2 x Push buttons, labeled A and B
  • 1 x Slide switch
  • Infrared receiver and transmitter - can receive and transmit any remote control codes, as well as send messages between Circuit Playground Expresses. Can also act as a proximity sensor.
  • 8 x alligator-clip friendly input/output pins
  • Includes I2C, UART, 8 pins that can do analog inputs, multiple PWM output
  • 7 pads can act as capacitive touch inputs and the 1 remaining is a true analog output
  • Green "ON" LED so you know its powered
  • Red "#13" LED for basic blinking
  • Reset button
  • ATSAMD21 ARM Cortex M0 Processor, running at 3.3V and 48MHz
  • 2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.
  • MicroUSB port for programming and debugging
  • USB port can act like serial port, keyboard, mouse, joystick or MIDI!

    Four Digit - Seven Segment Display - Red (display 7 segment red)
    Description:

    This lovely little (14.2mm) seven segment display provides excellent segment uniformity and is highly visible up to seven meters away. It's ultra bright, and provides great readability even in bright ambient light!

    It has four digits and a decimal point on each digit, designed for numeric output, so you can use it to add a clock, timer or counter into your next project.

    These displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit.

    This is an ultra bright RED colour.

    Specifications

    • 100mcd
    • 14.2mm (0.56") digit height
    • Color: red (630nm)
    • Common cathode display
    • Maximum power dissipation per segment: 66mW
    • Maximum pulse peak forward current per segment (1/10th duty cycle, 0.1ms pulse width): 100mA
    • Maximum forward current per segment: 20mA
    • Maximum reverse voltage: 5V
    • Maximum reverse current: 20µA
    • Typical forward voltage: 2.1V at 20mA
    • Maximum forward voltage: 2.5V at 20mA
    • Operating temperature range: -30°C - 70°C

    TEC1-12715 12V Peltier Plate Module (Peltier 12V 40x40)
    Description:

    Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity.

    This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or other block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortably cold we could not hold our finger to it.

    Note: It is imperative that a heat sink is used on the hot side of the module. Running the module without one can cause damage to this part. If it’s too hot to comfortably touch, you’re in the danger zone!

    Specifications:

    Model: TEC1-12715
    Color: white
