This device has been designed as an example application of an expandable system of modules for building mobile robots following the standards set out in the discussion on the Society Of Robots forum. These modules can be connected to each other using an i2c bus and Master modules like this one can also be connected via a UART to a wide variety of

equipment. (eg, PC serial and USB ports. ) This particular module acts as a Master node on the i2c bus and has one UART which can be connected to a PC serial port or USB port with the addition of a simple level shifter. With a little configuration and editing of the local_function in main. c the logic of the AVR ATmega8 I/O pins can be changed on the local module or any similar module connected to the i2c bus. All available I/O on the ATmega8 has been brought out to header pins making this a good platform for testing firmware for new module designs before thy have been built. This is *not* recommended as your first microcontroller project though. The additional complexity of an i2c networked microcontroller project puts it beyond the scope of novice builders. If on the other hand you have sucsessfuly built and programmed a microcontroller board in the past this module (and the other modules to come in the series) may be just what you are looking for. Welcome. You will need to be able to read a circuit diagram, source and purchase the parts, either make your own PCB or use some alternative (eg. stripboard), compile and upload the firmware to the microcontroller. If you have not done *all* of these tasks at some point in the past we recommend a simpler project, or at least wait until there a few finished module designs out there. As this is a template module rather than a finished one you will also have to do a little C...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
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....
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....
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....
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....
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,....
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....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
