REVISIONS:

12/03/15 Created version 0.1

19/03/15 Updated to work with V0.2 of the HCMAX7219 library

This is an example of how to use the Hobby Components serial 8 digit seven 7 

segment display module (HCMODU0082). To use this example sketch you will 

need to download and install the HCMAX7921 library available from the software

section of our support forum (forum.hobbycomponents.com) or on github:

(https://github.com/HobbyComponents)

The library assumes you are using one module. If you have more than one module

connected together then you will need to change the following line in the 

libraries HCMAX7219.h header file to the number of drivers you have connected:

#define NUMBEROFDRIVERS 1 <- Change this number

Description:

Using L298N as the control chip,the module has such characteristics as strong driving ability,low calorific value and strong anti-interference ability. This module can use built-in 78M05 for electric work via a driving power supply part. But to avoid the damage of the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage. Using large capacity filter capacitor, this module can follow current to protect diodes,and improve the reliability.

6~28V 3A Motor Speed Controller [B056]

https://www.youtube.com/watch?v=hdwnlHRdqRk

* Specs

This DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%. 

The motor speed controller can easily provide a continuous current of3A to your DC motor or other DC load. 

Main technical parameters: 

Input supply voltage:6V-28VDC 

The maximum output power: 80W 

The maximum continuous output current :3A 

Duty Cycle adjustable:0%-100% 

Operating instruction: 

1. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram. 

2. Connect a voltage of 10V-36V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits. 

3. You can now control the speed of the motor through potentiometer.
