Concept The customer’s demands were to develop and build a kit, consisting of a small mechatronic system with educational concept. In particular, he asked for a driverless robot for training purposes abroad. The idea behind this is that our customer needs a kit for sending it to partner schools around the world to help the

Concept of Touch LCD LC7981 using ATMega An on/off controller is the simplest form of a temperature control device. The output from the device is either on or off, with no middle state. An on-off controller will switch the output only when the temperature crosses the set-point. For heating control, the output is on when the

Sometimes it’s tempting to re-invent the wheel to make a device function exactly the way you want. I am re-visiting the field of homemade electrophysiology equipment, and although I’ve already published a home made electocardiograph (ECG), I wish to revisit that project and make it much more elegant, while also planning for a pulse oximeter, an electroencephalograph (EEG),

An ATtiny12 controller as a timer and some switching circuitry turns the doorbell off for 10 hours at the same time each day. The string of resistors across the top of the board are series connected to make a 728 Ohm 2 watt resistor. The slide switch is used to switch the circuit between the

Having done half a dozen V-USB tutorials I decided it’s time to whip up something cool. As USB keyboards were an area untouched. I decided to make a small USB HID keyboard device that types a password stored in EEPROM every time it’s attached. A new password can be generated just by tabbing CAPS LOCK

A simple, low component count phase locked loop that locks onto and detects the amplitude of an incoming baseband 7 bit Barker code using a switched resistor demodulator that is driven directly by a microcontroller’s output pins. Balanced modulators using resistors and a microcontroller’s output pins. Locking into oncoming Pseudo-noise (PN) stream. Microcontroller modulates its

My microcontroller-powered prime number generator/calculator is virtually complete! Although I’m planning on improving the software (better menus, the addition of sound, and implementation of a more efficient algorithm) and hardware (a better enclosure would be nice, battery/DC wall power, and a few LEDs on the bottom row are incorrectly wired), this device is currently functional

LED Dog Collar So this is a pretty simple project, but I thought it was a clever idea. I have 2 dogs, a lab and a lab mix. The lab “Sunshine” likes to runaway a lot if we let her outside at all. She always comes back, but we can’t find her whenever she leaves.

Around time when I was beginning to learn about microcontrollers. I had exchanged my laptop with a senior at college for his desktop – that’s because the only way I knew how to program an ATMEGA chip was through either a serial port or a parallel port. USB programmers were not available widely and were
