SUMMARY

The discussion focuses on building a radio-controlled car circuit using an 8-channel radio receiver and transmitter with a PIC microcontroller. Key components include the programmed microprocessors, which require prior programming to function. To power devices beyond LEDs, the use of a transistor to drive a relay is recommended. Participants emphasize the importance of sourcing components and programming availability for successful circuit implementation.

PREREQUISITES
  • Basic understanding of microcontrollers, specifically PIC microcontrollers.
  • Familiarity with radio frequency (RF) communication principles.
  • Knowledge of circuit design, including the use of transistors and relays.
  • Experience with programming microcontrollers.
NEXT STEPS
  • Research programming techniques for PIC microcontrollers.
  • Learn about RF communication protocols for remote control applications.
  • Explore transistor and relay integration in electronic circuits.
  • Investigate component sourcing for electronic projects, focusing on availability and pricing.
USEFUL FOR

Electronics enthusiasts, hobbyists building radio-controlled devices, and individuals interested in microcontroller programming and circuit design.

I took these two pictures from http://jap.hu/electronic/codec.html. They are an 8-channel radio receiver and transmitter using a PIC microcontroller.

I'm about as green as you get with electronics. My greatest accomplishment so far has been using a car's ignition coil to make a spark across some copper wires. I'd like to build this, so would anyone be able to tell me - what are all the parts in the diagrams, and where can I get them?

Also, how could I make the circuits light up something that takes more power than an LED?

Eventually, I'm going to create radio controls for a full-size old car. Gotta start somewhere :cool:

I marked some of the components.

However, the two microprocessors are programmed devices. This means they won't do anything unless you have them programmed.

So, you would have to return to the source to see if the chips were still available already programmed. This is where the programmer makes some money, because he can charge what the market would pay.

Also, how could I make the circuits light up something that takes more power than an LED?
You would use a transistor to drive a relay. But maybe try something a bit simpler first?
