Use foot switch to open Linux terminal using an Arduino

So here is how i made my foot pedal used to start Linux terminal using an Arduino. It's made because I am board of pressing the terminal icon with my mouse. P.S. Sorry for my English. I am from Croatia. Tools needed: -Soldering iron and some solder -Wire clippers or any other cutting tool -Screwdriver Parts needed: -Arduino system -Foot switch (I found mine in my workshop) -Wire -10k pull-down resistor or y ...

Ultrasonic Combination Switch using an Arduino

Time for a follow-up to the Single Button Combination Lock by creating another oddball type of switch/lock. To activate this switch we make use of a Parallax Ping))) Ultrasonic sensor, an Arduino-style board and some other hardware – to make a device that receives a four-number code which is made up of the distance between a hand and the sensor. If Arduino and ultrasonic sensors are new to you, please read ...

Sound Activated Switch

Description Clap switch/Sound-activated switch designed around op-amp, flip-flop and popular 555 IC. Switch avoids false triggering by using 2-clap sound. Clapping sound is received by a microphone, the microphone changes the sound wave to electrical wave which is further amplified by op-amp. 555 timer IC acts as mono-stable multi-vibrator then flip-flop changes the state of output relay on every two-clap s ...

Switch Statement used with serial input using Arduino

An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use switch to turn on one of several different LEDs based on a byte of data received serially. The sketch listens for serial ...

Arduino Switch Statement used with sensor input

An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use it to switch between four desired states of a photo resistor: really dark, dim, medium, and bright. This progr ...
