Cornell University ECE 4760 Designing with Microcontrollers Final Projects – Students in ECE 4760 at Cornell University were given the responsibility of choosing, designing and building a project using Atmel Mega644 microcontrollers. Projects this year include video object tracking, acoustic GPS navigator, and an automated rock band guitar player, as well as musical instruments and scientific devices. During the last 5 weeks of the semester in ECE 4760, Microcontroller Design, students have to combine sensors, actuators, microcontrollers, and mathematical techniques to build something.

101 AT Keyboard to ASCII Decoder: The Host to Keyboard Protocol is initiated by taking the KBD data line low. However to prevent the keyboard from sending data at the same Time that you attempt to send the keyboard data, it is common to take the KBD Clock line low for more than 60us. This is more than one bit length. Then the KBD data line is taken low, while the KBD clock line is released.
12C508 Smart Lock: The base sends a data sequence (the password) which is recognized by the key. The key checks the sequence and -if it recognizes it -sends to the base another data sequence, as an answer to the password. At the Time when the base gets a correct answer (which means that the key has been introduced), the relay is put into action, and it can command a number of consumers.

AC Vias Can Improve Decoupling: 04/28/03 Electronic Design – Ideas for Design / Good decoupling is nearly always essential in a world of mixed-signal designs that exhibit increasing speed, performance, and component density. There are cases, though, where proper decoupling is absolutely critical if the circuit is to deliver its..
Analog input circuit serves any microcontroller: 12/20/2001 EDN – Design Ideas / The simple ADC in Figure 1 is perfect for getting analog signals into a purely digital microcontroller. Using just five surface-mount parts, you can assemble it for less than 50 cents (1000), which is approximately half the cost of a single-chip-ADC approach in the same volume. Moreover, this design takes only one pin from the microcontroller to operate. .
