My goal is to design and build a (or many) custom RC car, using as many 3D printed components as I can. This will be my first project using a wireless remote control, so I have much to learn! This will probably be a lengthy project where I do a little work whenever I have some free time. I plan to use this blog to organize and document all of my research and development steps, mainly to prevent myself from having to repeat research from scratch every time I work on this project.

Components!
Based on information in the above links, I believe I need to purchase the following components:
HT12E Encoder integrated circuit – “Simply put, HT12E converts the parallel inputs into serial output. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. These 12 bits are divided into 8 address bits and 4 data bits.”
Amazon link ($5.85, Prime eligible)

HT12D Decoder integrated circuit – “In simple terms, HT12D converts the serial input into parallel outputs. It decodes the serial addresses and data received by, say, an RF receiver, into parallel data and sends them to output data pins.”
Amazon link ($7.26, NOT Prime eligible)

SMAKNĀ® 433Mhz Rf Transmitter and Receiver($6.66, Prime eligible)

L293D Motor Driver is a dual H-bridge motor driver and will drive two electric motors. The H-bridge allows voltage to be applied in either direction. Amazon link ($6.95, Prime eligible)
