Please keep in mind that many newer Arduino boards gets damaged when 5V is applied on the input pins. Voltage level conversion must be needed when using 5V input on not 5V tolerant boards. Also the ...

Pin (DB4 – DB7) on the LCD to the digital pins 6, 5, 4, 3 of the Arduino. Pin 15 (LED) on the LCD to 5V pin on the Arduino. Pin 16 (LED) on the LCD to ground on the Arduino through the 200-ohm ...

All the pins of this sensor module are digital, except VCC and Ground. The Pinout of a Micro SD Card Module is shown below: GND is the ground pin of the micro sd card module and it should be connected ...

Despite the differences in size and microcontroller, the Arduino Nano and Micro share some similar pinout configurations. They both have two GND pins, two reset pins, one AREF pin, and three power ...

Connect the servo motor with Arduino Digital pin D9 and with a 5volt power supply. This servo motor has a total of 3 input lines (GND, +5V & SIGNAL LINE). In this project, I have used a 4 x 4 matrix ...

Connect OBD2 module Rx to digital pin 1 that is used as Arduino Tx. For the first setup use 2.2 kOhm resistors in the Tx and Rx lines, so that no ports are destroyed, ... Arduino ...

This article describes the implementation of a digital frequency meter using Arduino Uno to determine the sinusoidal frequency signal in the range of 20Hz to 5kHz. The logic involves counting the ...

It is a 2 layers PCB board, last revision. The Arduino-Nano board is mounted on the bottom side and LCD on the top side of the board, preferably on female pin headers. This is more clear in 3D views ...

Arduino CLI For I/O Pin ... All in all, it’s a good addition to your digital tool box. On a completely unrelated note, we really like [Eric]’s USB cable with the right-angle micro ...
