AVR-Doper is an STK500 compatible In System Programmer (ISP) and High Voltage Serial Programmer (HVSP). It comes with a built-in USB to Serial adaptor to connect to modern host computers which often don’t have a serial interface. The project implements a low speed USB device in firmware only. No USB capable controller or converter is […]

The benefit using thermocouple sensor for measure temperature is it has wide range measurement (-200 °C to +1350 °C / -328 °F to +2462 °F range for Type K), inexpensive, interchangeable, and is supplied with standard connectors. To get temperature value from output of a thermocouple, you need high precision amplifier and proper compensation circuit

What is an AVR ? First of all AVR stands for: Advanced Virtual RISC. The founders are Alf Egil Bogen Vegard Wollan RISC (also forms AVR). An AVR is a small microcontroller (chip, IC) which is switching digitally (controller) by means of so called i/o’s (input/output pins) The i/o’s do all the digital switching. The
