Unlock a Door with your Fingerprint
by Kinoma @ instructables.com: We built a biometric fingerprint-controlled lock prototype. A fingerprint scanner is used to capture and store the fingerprints of authorized users. When the scanner recognizes a user, a solenoid plunger disengages and opens the lock. Unlock a Door...

How to program the ATtiny85 with the Arduino UNO board
by codebender_cc @ instructables.com: In this tutorial we will use an Arduino board as an ATtiny programmer. To do this we will use one Arduino UNO board as an ISP (programmer) and one ATtiny85 micro-controller. We will use Codebender - online Arduino IDE. With the...

Home automation with Telegram BOT
by lucadentella.it: The project I’m going to describe today it’s a sort of proof of concept that will demonstrate the possibility to remote control sensors and actuators (for example a couple of relays) via Telegram. Telegram is an instant messaging application, similar to...

Simple, Cheap Motor Controller
by TeamJaeger @ instructables.com: I've used this simple circuit several times to drive motors (like in my Stair Climbing robot) as well as solenoids. I originally picked it up from this instructable which is focused on controlling a solenoid. I wanted to isolate this circuit in its...
