First off, we'll use the Arduino's digital pin 8 to send a signal to the relay, through the other components. So hook up the pin 8 to a 1 kohm resistor. Why the resistor, because the transistor I'm using that will catch the signal from the pin no. 8 can't handle the full 5v...
Pin Plugs:Apin plug, otherwise known as a jumper wire is a simple wire with a single plug on the end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will...
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
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. ...
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 ...
I am using the Zigbee_On_Off_Switch example for Arduino with the ESP32-C6 module. I successfully integrated the wall light switches from Tuya and other manufacturers, and the switch On/Off works fine. However, the wall light switch I have is a 3-gang switch. The first switch works well...
In this tutorial I will show you how I built an Arduino based hexapod. As the name suggests, the hexapod has 6 legs but in addition to that, it also has...
If both the receiver and the Arduino have separate power sources, you do not need to connect a power wire between the two boards. Ground Next up is the ground connection. This one is easy: connect the grounds between the two boards – GND on the Arduino to ground on the RC receiver (...
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...
