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
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
