Arduino Motor Shield (L298N)

=================================================================================
Introduction
=================================================================================
This motor shield allows Arduino to drive two channel DC motors. It uses a L298N chip which deliveries output current up to 2A each channel. The speed control is achieved through conventional PWM which can be obtained from Arduino’s PWM output Pin 5 and 6. The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7.

The Motor shield can be powered directly from Arduino or from external power source. It is strongly encouraged to use external power supply to power the motor shield.

Step 2: Touch Sensor

====================================================================================
Touch Switch
====================================================================================

There are a number of different types of TOUCH PLATES and different effects
can be created by the circuit.

1. Touch a set of pads and the project turns on.
When the finger is removed, the circuit turns off.
The finger can touch the pads for any length of time.
We also include the feature where the circuit extends the ON period,
so the circuit stays on for a length of time after the finger is removed.
This is shown in Circuits A.

2. Touch a set of pads fairly quickly and the project turns on.
Touch the pads again for a short period of time and the circuit turns off.
This is called the "Flip-Flop" effect. If the finger is kept on the pads,
the circuit will turn on-off-on-off at a rate of about once per second.
This is shown in Circuits B.

3. Touch one set of pads to turn the circuit on and another set of pads to turn the circuit off.
This is shown in Circuits C.

Step 3: Limit Switch

I use three limit switches :
  • 1 for indicator door opened
  • 1 for indicator door closed
  • 1 for lamp

Step 4: LED Lamp

========================================================================
Calculating an LED resistor value
========================================================================
LED resistor circuit An LED must have a resistor connected in series to limit the current through the LED, otherwise it will burn out almost instantly.

The resistor value, R is given by:

R = (VS - VL) / I

VS = supply voltage
VL = LED voltage (usually 2V, but 4V for blue and white LEDs)
I = LED current (e.g. 10mA = 0.01A, or 20mA = 0.02A)
Make sure the LED current you choose is less than the maximum permitted and convert the current to amps (A) so the calculation will give the resistor value in ohms (ohm).
To convert mA to A divide the current in mA by 1000 because 1mA = 0.001A.

If the calculated value is not available choose the nearest standard resistor value which is greater, so that the current will be a little less than you chose. In fact you may wish to choose a greater resistor value to reduce the current (to increase battery life for example) but this will make the LED less bright.

For example
If the supply voltage VS = 9V, and you have a red LED (VL = 2V), requiring a current I = 20mA = 0.020A,
R = (9V - 2V) / 0.02A = 350ohm, so choose 390ohm (the nearest standard value which is greater).

Working out the LED resistor formula using Ohm's law
Ohm's law says that the resistance of the resistor, R = V/I, where:
  V = voltage across the resistor (= VS - VL in this case)
  I = the current through the resistor

So   R = (VS - VL) / I

===========================================================================
Connecting LEDs in series
===========================================================================
LEDs in series If you wish to have several LEDs on at the same time it may be possible to connect them in series. This prolongs battery life by lighting several LEDs with the same current as just one LED.

All the LEDs connected in series pass the same current so it is best if they are all the same type. The power supply must have sufficient voltage to provide about 2V for each LED (4V for blue and white) plus at least another 2V for the resistor. To work out a value for the resistor you must add up all the LED voltages and use this for VL.

Example calculations:
A red, a yellow and a green LED in series need a supply voltage of at least 3 × 2V + 2V = 8V, so a 9V battery would be ideal.
VL = 2V + 2V + 2V = 6V (the three LED voltages added up).
If the supply voltage VS is 9V and the current I must be 15mA = 0.015A,
Resistor R = (VS - VL) / I = (9 - 6) / 0.015 = 3 / 0.015 = 200ohm,
so choose R = 220ohm (the nearest standard value which is greater).

===========================================================================
Avoid connecting LEDs in parallel!
===========================================================================
Do not connect LEDs in parallel! Connecting several LEDs in parallel with just one resistor shared between them is generally not a good idea.

If the LEDs require slightly different voltages only the lowest voltage LED will light and it may be destroyed by the larger current flowing through it. Although identical LEDs can be successfully connected in parallel with one resistor this rarely offers any useful benefit because resistors are very cheap and the current used is the same as connecting the LEDs individually. If LEDs are in parallel each one should have its own resistor.
