L239D[DA1] E2 Toolpage

E2 Inc. ToolPage




I We used the L23D chip with Yourduino[DA2], and was very disappointed with the results. WHAT IS L239D??? It can be used and programmed to a basic robot to cause it to move forward, by command or with a sensor. [DA3]I simply used it as an RC car to pull a sled up-hill as part of Slæde. Another method for using this product, that we didn’t use, could be to program [DA4]it to move when a sensor detects movement.  You could use this for many purposes.

ETOOLBOX: Littlebits, the Cloudbit


“To put the power of electronics in the hands of everyone – Littlebits mission statement.

The productUsingLittlebits is a simple and easy way for anyone to make a simple circuit. You just have to magnetically connect the different Littlebits pieces and depending on what pieces you choose, the circuit will do something different.

Stepper Motor


Stepper Motor


A stepper motor is a type of motor which converts electricity into rotations. Each pulse of electricity causes the motor to turn. Stepper motors can also be very accurate in the speed and degrees of their rotation, making them very useful for moving an object to a specific degree. The difference between a stepper motor and a servo motor is that a servo motor uses a continuous rotation DC motor and a controller circuit while a stepper motor uses electromagnets placed around a gear to control its position.

Servo Motor


Servo Motor


A servo motor is a system of a motor and gears that can make precise movements. A servo motor has a range of movement of 180º. It’s movement is controlled by sending voltage through the yellow wire for a set amount of time and the servo interprets this and moves to the angle specified. This amount of control allows the servo motor to be used for many purposes including robotics, manufacturing and anything that needs to be moved to a precise location.

WorldClass Tech

NFC, or, Near Field Communication, allows for different devices to communicate through a radio chat. When the devices are brought within a close range of one another, they can communicate. NFC is almost like bluetooth, but in a smaller range. Unlike Bluetooth, NFC is often used where security is a concern. Because of the close range needed for NFC to connect, the devices must be practically next to each other, making it almost impossible for an eavesdropper to get any data being transferred. NFC is used in an endless amount of products today, such as smartphones, Google Wallet, and even the cards teachers swipe to get into our school.

Sound Sensor


Sound Sensor



The Adafruit Electret Microphone Amplifier is used to measure sound levels with your Arduino.


The Adafruit Electret Microphone Amplifier is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. Also, it is great for any project that requires measuring sound levels.

Solenoid: A cylindrical coil of wire acting as a magnet when carrying electric current.



A solenoid works by creating a magnetic field which attracts or repels a metal rod. The electromagnetic field allows the rod to retract or extend depending on how much, how frequently, and under what circumstances, you choose to send voltage out.


Solenoids can be used in automatic locking mechanisms, and are sometimes used in dialysis machines. They can also be used in the railway industry; “Anywhere that electrical power is required to achieve a movement becomes an application for a solenoid. Some general examples of use are locking, cutting, clamping, punching, positioning, diverting, holding or rotating.” (

How to Use Relays


(If you want to order relays, skip down to the section titled “Ordering relays”)


What are they?


Relays are on and off switches for electronics.


Why are they significant?


Higher powered circuits can ruin lower powered components. For example, powering a large motor with an Arduino board will not end well for the Arduino. The relay allows higher powered components to interact with lower powered components without the risk of damage.
