Output characteristics of a Bipolar Junction Transistor (BJT)

Launch BJT Output Characteristics GUI from SEELablet - > Electronics -> Transistors -> Transistor CE Prepare the experiment based on the schematic and instructions available in the help section. Resultant Data:  The base voltage (thereby base current) is varied and the corresponding I-V curves are plotted.


Stepper Motor Control

4-wire, 2-phase stepper motors can be controlled via digital outputs SQR1,2,3,4 . Since these outputs can only drive currents up to 20mA reliably, users must use push-pull drivers such as the L293B

Micro stepper motors shown below consume low amounts of

IMU Sensor for mechanics experiments

IMU Sensor for mechanics experiments

Inertial measurement units such as the MPU6050 can be used to study the motion of mechanical systems. The following code snippet demostrates extracting 3-axis data from the accelerometer, and gyroscope of the MPU6050 sensor

  Aim : To study the oscillations

Wireless Nodes : Battery powered intelligent subunits

Wireless Subunits are battery powered devices with unique communication addresses. They are capable of relaying sensor data, and also include various I/O capabilities.

The 2.4GHz transceiver, and small form factor make it an ideal replacement for interfacing various sensors to

Linear Optical Sensing Array

The SEELablet can be interfaced with a 3648 pixel linear Optical array (TCD1304) from Toshiba. Its large pixel size , and configurable integration times up to 1 second enable data acquisition under very low light conditions
