This instructable was designed for beginners in mind, but advanced users can easily adapt it to fit their needs and wants. It only uses a few common components, so you shouldn’t have much trouble putting this together. It’s a good waste of 5 minutes with a satisfying result (at least in my experience), and everything […]

Keyless Entry / Arduino
Keyless Entry System Enter the correct code into the keypad and the servo will unlock the door. Enter the incorrect code and Sorry you stay out. There was a couple of stipulations i wanted in my Keyless Entry system: Helper Light. A light that would come on whenever a key was pressed. Then off after […]
Ultrasonic Range Finder with an ATtiny85 using an Arduino
I’m here to show you how to use a HC-SR04 Ultrasonic Range Finder with an ATtiny85 as well as programming the ATtiny85 using the wonderful shield that randofo created. List of materials: ATtiny85 Programming Library Arduino Uno HC-SR04 Ultrasonic Range Finder and Library Jumper Wires Breadboard ATtiny85 Step 1: Program the Arduino Before you connect your shield to the Arduino […]
Auto Leveling Laser Cross using Arduino
So this Lazy Old Geek purchased a Laser Cross. I created a manual leveling Laser Cross to use for aligning stuff on my drill press: http://www.instructables.com/id/ManualLevelingLaserCross/ Well, being a Geek I decided to make an automated platform that adjusts automatically with an Arduino. Well, the picture may look a little scary but I’ll break it […]
Serial Servo Controller with Arduino
I’m going to show you how to use your Arduino to control up to 12 servos at once with minimal jitter. Using a simple serial interface you can control the position of up to 12 servo channels. Up to 10 snapshot positions can be saved and played back at any time. Start up values for […]
RGB LED Rainbow Fader using an Arduino
Introducing the RainBoard: A simple RGB LED Rainbow fader using an Arduino Uno and a few simple components. Believe it or not, we will control 45-channels of RGB LEDs at 32 brightness levels using only 3 digital pins from the Arduino! How is this possible you ask? By using two magic concepts: Shift Registers, and […]
Arduino LCD Metronome
Connecting the LCD The first step is to wire up the LCD. The HD44780 has 16 pins: Pin 1 – Vss Pin 2 – Vdd Pin 3 – Vo Pin 4 – RS Pin 5 – R/W Pin 6 – E Pin 7 – DB0 Pin 8 – DB1 Pin 9 – DB2 Pin 10 […]
Interfacing a Digital Micrometer to a Microcontroller
We had a project that required connection to a digital micrometer with a data output jack. The idea was to connect a microcontroller to the micrometer, to read the measurements and make decisions based on the readings. The micrometers that we used are made by Mitutoyo, and have a funky 52 character data stream in […]
Drive by wire go kart using Arduino
I just got a new go kart engine, i went from 6hp to 10hp. This new kohler engine I got I think was not built to put on a go kart, so I had some trouble finding a way to attach the gas petal. Well after a few days of not really figuring anything out, […]
Using The PCF8575 i2c i/o Expander To Read Inputs With Arduino
This Instructable will show you just how easy it is to add extra inputs to your Arduino. You can use this technique to add hundreds of extra inputs to your Arduino with only two wires by using a fancy communication protocol called i2c (eye-squared-see). What I have used… PCF8575 SMD to DIP breakout board Teensy-Arduino (any Arduino […]
