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:
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
