In this Arduino Relay Control Circuit we have used Arduino to control the relay via a BC547 transistor. We have connected transistor base to Arduino pin A0 through a 1k resistor. An AC bulb is used ...

The Arduino can only provide 40mA at 5V on its digital pins. Most motors require more current and/or voltage to operate. A transistor can act as a digital switch, enabling the Arduino to control loads ...

Microcontrollers—such as the ATmega328P chip that powers the venerable Arduino Uno as well as the Nano—allow you to take input from sensors, power LEDs, and send signals to other devices over ...

The sensors could detect pressure changes as small as 10 KPa – similar to a gentle touch such as typing on a keyboard. The finished “piezotronic transistor chip” may cover a modest area of less than a ...

Toshiba is adding 11 products to its line-up of new-generation transistor arrays equipped with DMOS FET outputs, capable of delivering high-voltage, large-current drive up to 50V/0.5A. The new devices ...
