Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will be used in this tutorial) and one other wire could be connected to the ground pin to power a tiny LED.Why the emphasis on a tiny LED?A microcontroller (and this ...
with diameter of 3mm, because that’s the approximate size of the cuts that the hot wire makes when passing through the Styrofoam. Here we can also set the cutting feedrate which depends on the hot wire itself and the hardness of the Styrofoam. I set it to 150 mm/m. ...
There is one more detail to be added to the head and that’s the antennas. For that purpose I used 3mm tick wire, which I cut it around 13cm in length and I slightly bend it to get the desired shape. Again I used few drops of AC glue to secure them to the head. Finally we ca...
If you are usinganalog VTX, and you’ve connected the SmartAudio or IRC Tramp wire forVTX control, then you should select “VTX (TBS SmartAudio)” or “VTX (IRC Tramp)” under Peripherals for that UART you have connected the VTX to. If you are usingHD VTX such as DJI / Avatar / HD...
How to Use a Magnetic Door Switch / Sensor With Arduino: In this tutorial we will use one magnetic - contact door sw / sensor and a buzzer for making a "noise" when a door is opened. Normally the reed is 'open' (no connection between the two wires). The
Push the wheel at the front and that activates a switch that turns on the power. But sometimes we want electrical and electronic circuits to be activated in other ways. Suppose you want to wire up a bank safe so it triggers an alarm whenever the door opens. How would that work in ...
Apart from the above components you will also need a few tools like, a soldering iron and solder, wire stripper, screwdriver set, hot glue gun, etc. Also, it is recommended to have a few additional components like a battery voltage monitor, power switch , and extra IR sensor module just...
Both motors can be driven simultaneously while set to a different speed and direction and can also power two brushed DC motors or one 4-wire two-phase stepper motor. All driver lines are protected by diodes from back-EMF. So how do you drive a DC motor with an Arduino and a Motor driv...

By combining inputs and outputs with some basic logic commands, you can make things happen automatically. Such as having alaser trigger wireto detect if anyone walks through a door, and making a ding-dong sound to alert a store clerk that a customer just entered. ...
