Two buttons Safety relay
This circuit turns on a relay when two buttons are pressed at the same time. The relay backs off after a few seconds, then the buttons have to be released and pressed again. This feature is often required in industrial...
jk electrical lighting sound systems
Utilizing a relay allows for a reduction in the length of thick wires that need to be routed, particularly through the firewall and beneath the dashboard. This approach also minimizes the necessity for a larger switch. However, when integrating with...
arduino 4 channel LCD voltmeter
An Arduino voltmeter that displays voltage on an LCD display. The voltmeter has 4 channels for measuring four different voltages.
The Arduino voltmeter utilizes an Arduino microcontroller to measure and display voltage levels on a Liquid Crystal Display (LCD). This device...
Remote Controlled Appliance Switch Circuit
The circuit diagram of a remote-controlled appliance switch circuit includes two main components: IC1 (NE 555) and IC2 (CD 4017).
The remote-controlled appliance switch circuit is designed to allow users to control electrical appliances wirelessly. The heart of this circuit is...
adding audio to arduino projects
A simple solution for enhancing sound output from a microcontroller is the LM386 series of amplifier chips, which provide high-quality audio for under one dollar. These chips can be used to create a functional MP3 docking station and serve as...
Arduino Tone 3
Power three force-sensitive resistors (FSRs) or any other analog sensor with 5V in parallel. Connect each sensor to analog pins 0-2, utilizing a 10K resistor as a reference to ground on each input line. The provided sketch reads three analog...
Universal Power Controller
Relay K1 features a low-impedance coil, while Relay K2 is equipped with a high-impedance coil. When a sensor opens, current flows through the coil of K1, activating it. This action opens the contacts of K1, thereby preventing the reclosure of...
arduino temperature and light sensor
This device transmits data regarding the state of an office to Twitter, as it is deemed slightly more relevant than sharing similar information about a residence. It holds potential significance for biodiversity-related activities, especially when integrated with long-range WiFi technologies....
Custom Arduino circuit not working
A circuit utilizes a keypad, a servo, and several LEDs, connected to an Arduino Uno. The objective was to integrate all components onto a single PCB, effectively creating a custom version of the Arduino. Upon startup, the red LED is...
