Today I ordered a few new parts for my robot project.
These are to be used to level convert between 5 and 3.3 Volts in order to use the Nokia 5110 screen I intend to place either on the robot itself.
The idea to use the 4050 is from http://learn.adafruit.com/nokia-5110-3310-monochrome-lcd I hope this is the right circuit.
The resonators are to be used together with the ATMEGA328 and ATMEGA8 chips order to improve from the internal 8Mhz clock to 16Mhz for the radio-beacons i intend to build for robot navigation.
I have used 16 Mhz crystals before but wanted to try something new. The resonators are a bit less precise, you can read about that here: http://jorisvr.nl/arduino_frequency.html. Main reason for using a resonator you do not need the two capacitors making the circuit a bit easier and they are cheap.
Power supply partsEl.lyt 100uF 50V 85C radial
El.lyt 10uF 50V 85C radial
These are to be used to build power-supplies for the radio-beacons. The circuit is here
These buttons are intended as reset buttons for the arduino board I built the other day. And perhaps also on the radio beacons.
The RGB-Led is to be used on the robot itself for presenting different states.
Other partsDIL-hållare 28-pin 0.3" These are to be used together with the atmega chips to avoid destroying the chip when soldering
I bought another ATMEGA328-PU DIP-28N Processor 20MHz 32kB chip
I bought a Level converter 3.3V/5V logik also to try out
