Decoding 4 buttons with two I/O's on AVR
Just the solution for AVR applications in which I/O is tight, such as the ATtiny12. This should work well on other kinds of controllers that have independently controlled I/O direction registers, such as PIC and 6805 controllers. This solution was...
Interfacing seven segment to microcontroller
The Tutorial shows how to interface 7-segment display to a microcontroller. Also explains how do display more than one 7-segment on same data lines using scanning method. 7 Seg displays are are basically 7 LED's. It will be much easier...
The simplest digital LCD voltmeter with AVR
This is likely the simplest digital voltmeter utilizing an Atmel AVR microcontroller and an LCD display. The circuit is managed by a microprocessor IO1 - AVR Atmel ATmega16A, ATmega16L, ATmega16, ATmega32A, or ATmega32. A program is available for free download...
Controlling high-current circuits
Digital output from a microcontroller is typically a low-amperage signal. For example, when a pin is set HIGH on the microcontroller (in Wiring/Arduino, it is digitalWrite(somePin, HIGH);), the voltage from that pin is usually +3.3V or +5V, with the current...
µP-Controlled Oscillator Delivers Rock-Bottom Distortion
Function generators are essential in the design, testing, and operation of encoders, modulators, demodulators, and measurement instruments. This document presents an economical method to construct a bus-controlled sinewave oscillator that exhibits exceptionally low distortion. The circuit produces a sinusoidal output...
AccelR8
The schematic shows that the AccelR8 only uses 3 ICs. An AVR 8515 microcontroller does the calculation work and controls the other circuits. A MAX603 controls voltage and power-on/power-off. And the chip that makes it all possible, the ADXL202 from...
POWER LINE MODEM FOR COMPUTER CONTROL
This circuit employs an 87C57 microcontroller along with several peripherals to convert X-10 power-line carrier-code formats from a personal computer for use with an X-10 power-line interface in a home-control system. Software details can be found in the reference.
The circuit...
An AVR microcontroller based Ethernet device
Ethernet has traditionally been a complex interface. All Ethernet chips up until now have had 100 pins or more, making them difficult to find in small quantities and challenging to use with microcontrollers that have limited memory. Microchip has revolutionized...
digital inputs interfacing with avr primer
A switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. A switch may be directly manipulated by a human as a control signal to a system or...
