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 be used in this tutorial) and one other wire could be connected to the ground pin to power atiny...
Use the red wire to connect the VCC from the UART to the VCC on the Arduino Use the black wire to connect the GND from the UART to the GND on the Arduino Use the green Wire to connect the SDA from the UART to the SDA on the Arduino And finally use the yellow wire to connect th...
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...
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). There ...
The Code for LCD Output To use this meter with an LCD screen, connect the LCD to your Arduino (seeHow to Set Up an LCD Display on an Arduinoif you need instructions). Pin 11 will be used for the LCD, so wire the capacitance meter using pin 8 instead of pin 11. Here’s the code...
I wanted to use only one side of the Arduino's Pins 0 to 13 since it’s the exact number of pins needed (and it would be simpler to connect all the wires on one side and not have spaghetti wire salad). But after few tests, the LED on Pin 13 was irritating so I decided not to...
In this tutorial I will show you how I built an Arduino 3D wire bending machine. This is actually a typical mechatronic system because it involves...
Arduino Speed Detector Circuit Diagram A simple breadboard based circuit diagram is shown below to help you with making the connections. As you can see the circuit is very simple and only consists of two IR sensors, an Arduino Uno, LCD display and a breadboard. ...
LCD 1602 have a command to clear the entire screen. voidlcd_clear(void){lcd_send_cmd(0x01);usleep(5000);} 0x01 can be used to clear the entire screen and set the cursor to the beginning, i.e at the 0x80 location. The command needs some time to execute, and therefore we have to...
