Atmega168 Timer interrupts

AVR Microcontrollers, Tutorials 18 Comments
This tutorial will teach you about the 8 and 16 bit timers on an ATmega168 microcontroller. Because the ATmega168 is very similar to the ATmega48, ATmega88 and ATmega328, the examples should also work on these. For other AVR microcontrollers the general principles will apply but the specifics may vary. What are the 8 and 16...

We are very excited about these DS18B20 programmable temperature Sensors from Maxim. They use a 1-Wire bus that allows multiple sensors to be daisy chained together. Each sensor has a unique serial number which allows it be be addressed independently of the other sensors on the bus. These LM358 op amps are a great dual...

External Interrupts on an ATmega168

AVR Microcontrollers, Tutorials 12 Comments
This tutorial will teach you how to use external and pin change interrupts on an AVR microcontroller. I will be using an ATmega168. The general principles apply to other AVR microcontrollers, but the specific vary greatly. What is an Interrupt? Imagine your are sitting at your computer, reading this post. The phone rings and you...
