5 volts will freely flow through yourcircuit, and when it is not pressed, the input pin will be connected to ground through the 10k ohm resistor. This is a digital input, meaning that the switch can only be in either an on state (seen by your Arduino as a ...
Now that your setup has been completed, move into the main loop of your code. When your button is not pressed, the internal pull-up resistor connects to 5 volts. This causes the Arduino to report "1" or HIGH. When the button is pressed, the Arduino pin is pulled to ground, causing ...
Hello guys, today we are going to have a look on, How I made an Arduino based FM and then turn its circuit into a fully functional PCB. In this tutorial you will learn, basic FM working, Arduino code for this FM, range, speakers, antenna and amplifiers used in this circuit. This ty...
The Arduino uses 5V logic but the callipers output 1.5V logic. This is a bit of a bodge and may not always work, really a proper logic level conversion circuit should be used but the flowing is a simple hack that worked well with my Arduino: My Arduino changed between logic high and ...

While there are a few libraries for the MCP series of digital potentiometers, it is so easy to use them with SPI that a dedicated library is unnecessary. You can code for these devices using the SPI library, which is included with the Arduino IDE. ...

Here we will discuss the operation of pulse-width-modulation to DC conversion and use the idea to construct a variable Arduino based DC power supply.Fig. 1 illustrates using a LM358 in conjunction with a low-pass filter (10uF cap, 4.7K resistor) to produce a 0-5V output proportional to ...
In excess to your Arduino Board, you would require the following fundamental items: Hardware A momentary switch, button, or a push-to-ON switch 10k, 1/4 watt ohm resistor breadboard hook-up or jumper wire links. Circuit Operation The operation may be done with the following steps: ...
