Контроллер вентилятора на ATtiny13 | До 8-ми датчиков температуры!

An upgrade of the previous fan controller project (based on ATtiny10). Powered by a single supply of 12-38 V. Sound alerts. Up to 8 DS18B20 linked temperature sensors. Controlling the rotation and work with 2-, 3- and 4-wire fans. ** English subtitles available ** ATtiny13 has 64 bytes of EEPROM on board, which we will use to store the serial numbers of the connected sensors. As in the previous project, the controller is able to automatically determine whether the fan connected to it can be controlled by PWM. And now it is able to poll consistently up to eight DS18B20 sensors and adjust the fan speed (or turn it on/off) based on the readings of the hottest of the sensors. To get started, we will need the ATtiny13 chip itself, USBasp programmer, a pair of DS18B20 chips, four-wire fan, breadboard, a bundle of wires and an Arduino IDE.
