STHS Computer Technology
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 it is controlling. You
Bots Circuit Designs
Using a PIC12F675, up to 5 outputs can be switched sequentially using a standard Remote Control pulse input of between 1 to 2 ms. Although any RC channel input can be used, it is especially useful when used with the rotary knob channels (usually 5 and above on RC airplane remote). The knob can be rotated to a certain position, selecting which outp
Robot Train Cruise Control
Picture three or four small engines occupying the same loop of track and keeping a safe distance as they go round and round. I am sure that many of us have tried this with radio controlled engines but it can be a constant battle to keep them apart especially if you have many grades to contend with. Now picture the same group of engines automatical

Robot Trains in the Garden motor control circuit
I have only been actively involved with garden railroading for a little over one year but have found it to be a wonderful way to use the skills and interests that I have developed over the years in other hobbies. For example, I used my love of woodworking to help me design and construct two scratch built bridges and nearly 100 trestle bents to sup
Our strategy was based on our ability to traverse complex, tape ridden terrain in the most efficient way possible: with superior speed. Even though we only went for goal #1, which was the lowest scoring goal, by acting quickly and finishing the game early, we hoped to limit the other team`s points. Our mechanical and electrical designs were cen
Line Following Robot Sensor
This Line Following Robot sensor or surface scanner for robots is a very simple, stamp-sized, short range (5-10mm) Infrared proximity detector wired around a standard reflective opto-sensor CNY70(IC1). In some disciplines, a line following robot or an electronic toy vehicle go along a predrawn black line on a white surface. In such devices, a surf
After fail finishing the robot for the competition, I stopped updating my blog for a while. This is because I feel a bit disappointed for not be able to finish the robot in time. Today I am going to update the result of the entire work we hove done so far. The reason why we change the motor driver was because we found that the L293D can cause some

Servomotor-based mobile robot control
Mobile robots are used in many industrial, commercial, research, and hobby applications. This project is about the control of a mobile robot using servomotors. The robot used in this project is the base of a popular mobile robot known as Boe Bot, developed by Parallax ( and The basic robot is controlled from a Basic Stamp controller (Trademark of
Line Follower Robot
Designing a simple and yet functional Line Follower Robot (LFR) is always a fascinating and challenging subject to be learned, the LFR actually could be implemented in many ways start from a simple two transistors to a sophisticated PID (Proportional, Integrate and Differential) which take advantage of the programmable feature of microcontroller t

Making a Line Sensor using IR Receiver
A line follower robot, or a LFR in short, is a simple autonomous robot that optically tracks a line made on the surface of the floor. That means you have an arbitrary line drawn on the floor and the robot tracks it by moving right along it! The line is sensed using a piece of hardware called a line sensor. A line sensor can be easily made using a
Turning analog inputs into multi-switch digital inputs
I am interested in creating an interactive LED gameboard of some kind (or even a sort of "Stargate" DHD-type sci-fi prop!), where each square or tile is lit up from below by either a single white LED or an RGB combo. It always occurred to me that I`d love it if I could have each tile be responsive to touch. Nothing fancy, just a simple on/off...

The Synthetic Psychology of Sound Localization
Although the voltage across the two pins of our microphone will fluctuate based on the input sound, we would like to amplify this so that the Arduino can actually read the signal. This can be a bit of a complex circuit to think about at first to we will build it up slowly. This figure gives an overview of what the circuit will do: First, the volta
TDA2822 Audio Amplifier
Usually the project is a variation on the POV toy, which you see around online all of the time as a beginner electronics project. However, we decided to deviate from our traditional path this year and create our own synthesizer kit, with an SPI DAC, Audio Amplifier, Microcontroller and some buttons. There is also a possibility for programming in...
This is just my attempt in making the simplest and kinda smallest photovore. Well, it`s not that good-looking though, but it`s a great start for some beginners. It`s also my own version of Dozer photovore. Right here! Woah, it`s been a long time since my last update here my friends! Anyways, here`s my latest robot that I`ve built. Its name is...

If there is no light falling on the diode it will exert a high impedance(resistance). if light falls on the diode resistance of the diode willdecreased. (almost short circuit) in case of a black body or space(no objectin front of sensor) thenno light falls on the diode so it will act like a open circuit. so voltage at output will be almost equal...

Ultrasonic distance finder circuit
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to find something potentially valuable, hidden a few centimeters below the soil. So many...
Fully automatic watering circuit for flower pots
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This circuit comes as a solution to this problem. Depending on humidity of the pot at...

The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the circuit of this metal detector, it is possible to detect a metal coin in depth of 90 to...
Sub-Harmonic Bass Converter for Electric Guitars
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the calibration of the rope. This arrangement still exists in some yachts. The big...
