these AC-powered relays may be susceptible to many voltage sags that do not affect other elements of a control system. Therefore, they present an “Achilles heel” that may cause an entire machine, ...

Connect the GND and VCC pin of this module to the GND and VCC of Arduino Uno. Let's connect the SPI pins ... Wireless Controlled Shutter Button for DSLR using Arduino and nRF24L01 Control your DSLR ...

With just an Arduino UNO R4 and a few lines of code, you can make that happen—no expensive GSM module required. To make Arduino send a text message to your phone without using a GSM module, you don’t ...

One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino. The 4…20 mA standard was introduced a few decades ago, to replace the existing 3 ...

Sequential Mode: Runs patterns in order (1 → 2 → 3 ...). The setRelays() function allows dynamic control over multiple relays by setting their ON/OFF states based on an input array. It simplifies ...

The AR488 GPIB controller is an Arduino-based controller for interfacing with IEEE488 GPIB devices via USB. This work was inspired by and has been based on the work originally released by Emanuele ...

Methods: We investigated the independent and combined contributions of the inner and outer retinal photoreceptor inputs to the afferent pupil pathway in participants with trichromatic color vision ...

[Gilad] tipped us about his latest project, where he adds plenty of pneumatics and electronics into his wife’s car to remote control it ... turning the wheel. The Arduino code tells us that ...

The Arduino Team presented some new products at Maker Faire this weekend. It’s a significant update. The Arduino UNO and Arduino ... transistor, relay, power MOSFET, push button, LEDs and ...
