Car wireless alarm
This FM radio-controlled anti-theft alarm can be used with any vehicle having a 6- to 12-volt DC supply system. The mini VHF, FM transmitter is fitted in the vehicle at night when it is parked in the car porch or...
Serial Servo Controller with Arduino
This document explains how to utilize an Arduino to control up to 12 servos simultaneously with minimal jitter. A straightforward serial interface allows for the control of the position of these 12 servo channels. Additionally, it is possible to save...
Wireless switch using arduino and a mac circuit
The capability to control lights and fans wirelessly has transitioned from an expensive luxury to widely accessible consumer solutions. Nevertheless, creating a custom solution remains an engaging project for hobbyists and tinkerers. RobotGrrl has developed user-friendly libraries aimed at addressing...
Arduino LED blinking with variable speed
To achieve LED blinking at varying speeds, it is essential to modify the delay time for the LED's ON and OFF states. The fundamental approach involves changing the argument of the delay function based on time. Initially, the variable j...
arduino uno parking sensor
Required components include an Arduino Uno, an HD44780 Character LCD, a PING))) Ultrasonic Distance Sensor, a speaker cone from an old computer, a breadboard, wires, resistors, colored LEDs, and Arduino software. The provided schematic illustrates the parking sensor circuit. A...
rfid with arduino
This tutorial provides guidance on integrating RFID functionality into a project using the RDM630 module from Seeed Studio, specifically its UART version. The module is mounted on a compact board with pre-soldered connectors, making it compatible with breadboards. To set...
Arduino-Board
When starting with Arduino, one often accumulates more Arduino boards than RS232 or USB ports available on the computer. Therefore, it is more practical to use an external signal level converter rather than placing it directly on the Arduino board....
Hard but soft power switch for Arduino
The power controller module in the system receives input directly from a momentary switch and utilizes this input to toggle a relay, which supplies mains power to the system's transformers. The controller circuit operates at 12V, a choice made to...
Arduino While Loop
Sometimes, it is necessary for a program to halt execution while a specific condition remains true. This can be accomplished using a while loop. The following example illustrates the application of a while loop to calibrate the value of an...
