The final step is to connect your motor to your blinds or curtain hardware. This will largely depend on the product you are using, and remember that heavy curtain and blind hardware will require a higher torque motor. You may wish to switch over to a 12V motor at this point.
Note
If you connect the 12V power supply and motor, remember to disconnect the power pins on the motor shield.
Let's now look at the delay values that we have to set in the loop() function.
Our application has a delay of 5 seconds in the conditional statement that opens and closes the blinds. This was an arbitrary amount we set when creating our application. When you attach your motor to the blinds or curtains, you will need to calculate the number of seconds required to open and shut them. You can also adjust the values in the pwm() function to either speed up or slow down your motor.
Once you have set up the hardware, try experimenting with these values until you adjust...
