    Humidity Sensor with DHT11 and PIC16F676

    Hello Guys I am trying to develop a humidity sensor with DHT11 for my bathroom. The DHT11 Sensor reads the humidity and sends it to the PIC, if the humidity is over 75% a LED should light up. If its under 75% the LED is off. But I have two problems. First

    *Interesting:* If I upload the same code to a programming board with the PIC18F45K22 and add the DHT11 Sensor, everything works as it should. Sadly I am not able to use this programming board for my project. Therefore I would like to do it with the PIC16F676. Have you guys any idea, how i can fix
