    A device which has two OneWire data channels on the same microcontroller. One channel will be a slave, which can send data as a normal OneWire slave. The other channel can act as a OneWire master. Ideally this will be run on an ATTINY microcontroller. The advantage of OneWire is that power and data are transmitted along a single wire, with only a ground return to complete the power and data circui...

    We need to control LEDs using remote using attiny13a. The project involves decoding the IR signal sent from the remote and describe exactly where and how they are used in the program. It also involves that what parameters need to be changed if we change/replace the remote The attiny 13a must be programmed using arduino uno.

    Hi, i need a tiny sketch for an ATTiny85 Digistump. The ATTiny must switch an output (Pin5) to low state every 10 minutes with millis() (Pin5 is 'high' as default). After the 'low' state, the ATTiny has to wait for a 'high' signal at the input (Pin2). If Pin2 is 'high' -> Pin5 needs to be 'high' again. And that's the loop. The ATTiny must ...

    I need code developed for use in the Arduino IDE (assembly language includes ok) specifically for the ATTiny10 that would turn two lights on and off at random intervals. Since the ATTiny does not have a random number generator, you will need to develop a way to create pseudorandom on/off times as part of this project. The Tiny10 has two PWM outputs, so you will use these to control two LEDs. Ea...
