ATTiny13 Interrupt Issue

I have recently been working on a project that I had initially been designing with an Arduino Nano, and I was able to create functioning code for my application, but for cost / space reduction I decided to port the application to an ATTiny13…

How to create a 1-hour timer with an ATtiny13A microcontroller?

I want to control an AC load such that it powers on for 1 minute, then turns off for 1 hour, then on again for 1 min, and so on, in a loop. I just modified the blink sketch to do: Turn A1 on Then delay for 60,000 ms Then turn A1 off Then delay for…

Low Power Pin Change Detection (ATtiny)

I want to use an ATtiny as data logger for the opening and closing of a door/window. For that I am using a reed-switch. Since I want to run it from a 3V coin battery, long term power consumption is crucial. Therefore the ATtiny (currently 13A) is in…

Can I connect a voltage, higher that the 1.1V bandgap voltage, to an ADC pin

Can I (attempt to) measure a voltage that is higher that the ADCs Vref, without damaging my IC? I'm trying to measure the battery voltage using a resistive divider, and using the internal 1.1V bandgap voltage. I selected the resistors so the voltage…

Uploading .hex to ATTiny13 using Arduino

I would like to upload a .hex to ATTiny13V (or '13A) using Arduino Uno R3. I think I know everything to do, but ATTiny13 ISP support and Arduino IDE is a bit search-and-find, and I have some grey-areas in my understanding of how this all works…

Can I create a serial.read command with the arduino code alone?

I am trying to manipulate a project and the simplest way to do what I am trying to do would be to use the existing code. This code is designed to take an input from the serial monitor using serial.read() and manipulate it. For example if I type…
