Arduino Uno R3

Arduino UNO in Bangladesh The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.

Description
Description: The EasyDriver is a simple to use stepper motor driver, compatible 
with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you 
solder SJ2 closed on the EasyDriver). The EasyDriver requires a 6V to 30V supply 
to power the motor and can power any voltage of stepper motor. The EasyDriver 
has an on board voltage regulator for the digital interface that can be set to 5V or 
3.3V. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision 
motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, 
or 8 wire stepper motors.
 
This EasyDriver V4.5 has been co-designed with Brian Schmalz. It provides much more 
flexibility and control over your stepper motor, when compared to older versions. The 
microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments 
to the microstepping resolution. The sleep and enable pins are also broken out for further
control.
 
Note: Do not connect or disconnect a motor while the driver is energized. This will cause 
permanent damage to the A3967 IC.
 
Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes 
back to them for product support and continued development.
 
Features:
  • A3967 Microstepping Driver
  • MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter 
       and eighth steps (defaults to eighth)
  • Compatible with 4, 6, and 8 wire stepper motors of any voltage
  • Adjustable current control from 150mA/phase to 700mA/phase
  • Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds

Waterproof DS18B20 Digital Thermal Probe or Sensor

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 any signal degradation even over long distances!
