Vibration Motor ON/OFF & PWM Tests with Arduino! To test the above vibration motor driver circuit, I picked an Arduino Uno and executed the basic “Blink” example code after linking Arduino’s D13 ...

Hi guys, I need two buzzers alternating on / off on one pin. Is it possible to get ‘opposite’ transistors in series? One that grounds when the base goes high, one that grounds on low? In that ...

[Lee] took off the vibration motor and used it as an output port for a simple program to dump the ROM. An Arduino picked up the data at a low baud rate and produced an output file.

When the Arduino detects the rumble motor signal switching on, it turns on a relay, supplying power to a hefty one horsepower induction motor, fitted with an eccentric weight.

Cover up your webcam, disable microphone access and put on your tinfoil hat — but it won't make any difference, because the Illuminati can get at you through your phone's vibration motor now ...
