This article and circuit diagram show how to connect a buzzer to an Arduino when the buzzer operates at a different voltage to the Arduino. The buzzer may operate at 9V, 12V or some other voltage. Arduinos such as the Arduino Uno operate from 5V. All the voltages referred to here are D.C. voltages (direct […]

The Tog base module contains a densely packed PCB assembly, battery, and modular expansion bus in a ultra-small plastic enclosure. The base module can operate standalone with no additional components required. The front of the Tog enclosure is transparent to allow the internal LED to be visible and allow the optical sensor to detect button […]

I  did the following steps: 1) Hardware: Connect the MLX90614 (refer to the datasheet) as follows: Pin 1 on MLX (SCL) connect to ANALOG pin 5 on Arduino Pin 2 on MLX (SDA) connect to ANALOG pin 4 on Arduino Pin 3 on MLX (VDD) connect to 3.3V on Arduino Pin 4 on MLX (VSS) […]

I came across a stash of iButton T-sense 1-wire sensors.. so I grabbed a couple and decided to check out 1-wire. Maxim makes a 1-wire device called the DS18B20. It’s a 9-12 bit temperature sensor with the possibility of being powered by parasitic power from the data line. This cuts the signal path down to a […]

Steps On the breadboard, build two bi-directional motor control circuits (also known as “H-bridge”) circuits. These circuits will control the two DC motors that drive the wheels. Each circuit will have two wires from the Arduino (one for forward, one for backward) to control the circuit, and two wires from the single DC motor that […]

Thank you helped me a lot just by opening that instructable !! Now enjoy my instructable. This is my first instructable. I show you updates on my cnc machine which will cost about 200 euro’s for still decent quality. Don’t hate if you don’t like this instructable, I’m just an 18 years old student from […]

More on Resistors and LEDs Software Comments Variables Procedures References Project 1.Overview As mentioned earlier, Arduino consists of two major parts: the hardware (the Arduino board) and the Software (the IDE). The advantage of using the Arduino is […]

LED Panels A few years ago I built a red-only 32 pixels high, 96 pixels wide LED Matrix, and due to all the positive responses I sought out to do it again the year after with a bigger better matrix. I did some research into affordable solutions, and as usual ended up with Chinese vendors. […]

This circuit is designed for tracking the location of vehicles. Most oftracking systems are made by using GPS. This is very simple and cheap. Tracking systems are mostly used by fleet operators for tracking a vehicle location, routing and others. This is a very good method for preventing our vehicles from stolen. This tracking system […]

This project describes how you can build a mobile real time GPS tracker with integrated Google Maps. I began this project mainly to see if I can integrate all the different pieces of hardware and software to make a workable solution, and it took some time, but finally when everything was said and done, it […]
