Arduino: How to wire a relay Here's my quick tutorial on how to hook up a relay to an Arduino; specifically an electromagnet switch relay from Omron, the G5SB-14. You can use the relay that's referred to with AC voltage, i.e., to turn on and off mains-powered applications such as...
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...
To show you how to wire the relay, let’s build a temperature controlled relay circuit that will turn off a light bulb when the temperature of a thermistor reaches 150°F.Thermistorsare really useful with 5V relays. You can use them to turn off a large motor if gets too hot or turn o...
As we know, if we connect a LED to the digital output of Arduino, and make this pin output High or Low, the LED would be on/off. This is the first step to learn Arduino. But sometimes, we want to control some modules that works in high voltage/large current, for example, I want...
To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. Here's how! To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. Here's how! Circuits that operate...
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 (...
Arduino Tutorials Arduino Basic Usage How To Choose The Right Cable How To Choose The Right Cable A Bad Example Here we will introduce a variety of cables that Seeed offers. When you make a demo, it's hard to avoid jumping a wire. To be honest, I hate jump a wire, it's really...
The DHT11 uses just one signal wire to transmit data to the Arduino. Power comes from separate 5V and ground wires. A 10K Ohm pull-up resistor is needed between the signal line and 5V line to make sure the signal level stays high by default (see the datasheet for more info). ...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
