Hi Friends, Here i am using the RTC DS 3231 (which works on the I2C protocol) to wake up my Arduino UNO board from sleep whenever the Alarm occurs. When the Alarm occurs an Interrupt is being triggered on the INT pin of the RTC and this interrupt wakes up the arduino from sleep.

este projeto consiste em configurar a velocidade de um motor(PWM) e deixar essa configuração salva na EEPROM

Всем привет. Сегодня я расскажу о том, как подключить SD-карту к Arduino. Подпишись и поставь лайк! Мой сайт – http://michael.com.ua/
