Watch Link Remover
Step 1: Parts
There’s a couple basic parts needed to get this started, such as 22mm wire, solder, a solder iron, 1k ohm resistors, a transistor, and wire jumpers for an arduino. Then of course you’ll need the arduino, an uno rev 3 or something similar will work fine. Then you’re gonna get a button to activate the arduino and a push pull solenoid which will physically remove the link pin.
Step 3: Step 3
Upload the blink program to the arduino so that the output from pin 13 blinks every second while the arduino is activated.
