Simple Solenoid Tutorial

In my latest video tutorial I show you how to control a pull type solenoid switch with a push button using the D1 mini.

Solenoid switches have a wide range of uses from water/air valves to electrical relays. In a future project I use a pull type solenoid similar to the one used here to act as a locking mechanism.

The parts you will require are as follows:

• 4.5V 10g Pull type solenoid
• Wemos D1 Mini
• Push Button
• TIP120 Transistor
• 1k Resistor
• Diode

The schematic is as follows:
