Easy Motor Controller
Easy Motor Controller allows to control the speed and the direction of rotation of a DC motor through three different possible inputs: analog (potentiometer), radio control RC, I2C digital communication.
Its use is very simple and you do not have to do anything, the type of input used is detected automatically when the board is powered.
To optimize the response to RC commands you also have the calibration function on the receiver signals.
The Easy Motor Controller provides two separate power supplies, one for the motor and the other one for the logic part; the latter can be pulled out through a jumper directly from that of the motor or alternatively from the BEC circuit of the RC receiver.
For the I2C communication, there are two different slave addresses selectable through a jumper, and in this way it is possible to use two Easy Motor Controllers on the same serial line, and then control them by using a single external controller.
The possibility of using two limit microswitches that will act as a protection, interrupting the movement of the motor in the two possible directions when the pressure of the microswitch is detected, completes the functions on the board.
To fix the board there are 4 holes of 3.2 mm with a distance of 28mm from each other.

As soon as the board is turned on the L led will start to flash rapidly to indicate that the recognition of the type of input is in progress.
This phase lasts for a maximum of 2 seconds, during which the board will wait for a valid communication or a signal from the RC connector. If neither the I2C communication nor the RC signal are detected, the board will use the analog signal of the potentiometer as input.
After this phase, the led will turn off and then will flash again much more slowly, taking only 1, 2 or 3 flashes to indicate the type of input detected, according to the model of Table 1. flash number Input type 1 I2C 2 RC 3 Analogic Tab.1 – Input type At this point, in the case of I2C or analog input, the L led will light steadily to indicate that the board is ready, and the motor will respond to your commands.
On the other hand, if you are using a RC receiver, the calibration phase useful to measure the characteristics of the receiver will start.
During the calibration phase it is important to start with the joystick on the remote control positioned approximately in the center. The L led will flash quickly and the board will wait until the user moves the joystick to its maximum position; once calculated this value, the board will turn off the led for about one second and then let it flash again at a lower speed waiting for the user to move the joystick in its lowest position.
Once calculated the signal range, to prevent the motor from starting to move at a high speed the L led will be made flash quickly again and the board will wait until the joystick is brought back to its central position; only then the led will turn on steadily to indicate that the board is ready and the motor will respond to your commands.
Now the calibration is finished and the board will be able to take advantage of the RC signal complete swing of your receiver.
