Homemade ‘Universal Remote 7000’ Built with ATmega328P (Arduino-Compatible)

Thanks to Drew Fustini for posting this on OSH Park! (Similar-but-different, this project reminds me of a project I worked on several years ago with Tony DiCola who designed an Arduino Yún-based Smart Remote Control – I then used that project to sniff a legitimate remote control’s button signals so I could backup the remote’s code and share that code with others who might also have lost their remote for the same appliance.)

A couple years ago my TV remote broke. I had used one of those universal remote phone apps as an alternative for a while, but that just got really frustrating. Without the tactile feel of buttons it was too easy to press wrong buttons on my smart phone; accidentally pressing mute, stop or changing the channel / input, etc. I considered just ordering a cheap replacement remote off of Ebay for a few dollars but part of me wanted to take advantage of the situation and make one from scratch using the atmega328p chip used on the famous Arduino Uno. I had been tinkering with the atmega chip quite a bit at the time and was also exploring the process of designing circuit boards using cad software. I loved the idea of designing a circuit board from scratch & filling it with circuits. This seemed like the perfect project for me – being able to use my beloved arduino chip, design and populate a circuit board with circuits & fashion some kind of project case (altoids tin) to put it all in. I went for it.

I’m also digging this early prototype, which reminds me of the size of those ‘big button’ TV remotes:

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
