This project involves a scrolling LED display composed of 64 LEDs arranged in a matrix configuration. The anodes of the LEDs are driven by a driver IC, UDN2981, while the cathodes are controlled using the ULN2803. An Atmega8515 microcontroller...
The Atmega 128 is similar to other AVR microcontrollers. It is in-system programmable (ISP). An earlier article discussed the AVR ISP programmer, which utilizes a 74HC244 buffer for safety when programming the AVR. However, if a programmer for the...
In the article you will find a description of the universal PIC programmer, which suggested the involvement of Jens Madsen Dyekjar. Program allows districts PIC12C5XX, 12C67X, 16C55X, 16C61, 16C62X, 16C71, 16C71X, 16C8X, 16F8X, serial EEPROM 24Cxx. It allows to...
A tiny speedometer/trip computer was constructed using an Atmel ATTiny2313 microcontroller and an HD44780-compatible character LCD display, along with a reed switch and magnets. This device measured the speed of a soapbox derby cart by attaching a permanent magnet...
The digital display temperature detection circuit utilizes a precision digital display to indicate temperature readings. The circuit employs the MC1403, which outputs a reference voltage, with the potentiometer RP5 setting the reference value for the inverting terminal (a) of...
Infrared light is electromagnetic radiation with longer wavelengths than those of visible light. It is utilized in various industrial, scientific, and medical applications. Most remote controllers employ infrared light to transmit information. This protocol was developed by Philips using...
