So you have a solenoid that you want to use as an electric door lock, or some other kind of actuator with your Arduino. But, here’s the problem: too high a current for the Arduino to source, and too high of a voltage to drive.
Well fear not, using a simple transistor we can set up the solenoid to work hand in hard with your arduino. If you are interested in purchasing this solenoid, there is a link in the description of my Slow Boat fro
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
