What do resistors do and why are they necessary when working with electronic components?
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
What is the function resistor?
Resistor Definition and Symbol A resistor is a passive electrical component with the primary function to limit the flow of electric current.
How to use Solarbotics automatic window blinds controller?
Right click on the schematic and choose “save as” to save a copy to your computer. It was a simple matter to work out the mechanics of opening and closing my blinds with the Solarbotics GM3 Gear Motor. The only modification I had to make was to drill a small hole in the shaft.
How can I control my Arduino roller blinds?
The complete ESP8266 code for this Blind Control Project can be found at the bottom of this page. Our program has to wait for a command from the blynk application and based on that command, we have to rotate the stepper motor either in a clockwise direction or in an anti-clockwise direction.
Are there any motorized blinds with AC motor?
Motorized roller shade, dual shade, curtain, cellular shade, woven wood, etc. Different window coverings are available with specific motor types and not all are available with an AC motor. For this article we will focus on roller shades with an AC motor.
What kind of adapter is used for IoT blind control?
The complete circuit diagram for the IoT Blind control project is shown below. We have used a 12V adapter to power the entire setup; the LM1117-3.3V regulator converts the 12V to 3.3V which can be used to power the NodeMCU board. The stepper motor driver module is directly powered from the 12V adapter.
