Arduino question: can one ardy read the serial print of another and use it? Details inside.

Use software serial if you still want debugging through the serial monitor. The buffer holds all data that it receives, and gets rid of it after it has been read.

Just connect the TX pin on the transmitter to the RX pin on the receiver. The data will be stored in a buffer (think of it as temporary storage for received info) until it is read in software with Serial.read().

I'm not sure if I understand you correctly but when you print to the serial monitor, the signal is also present on the TX and RX pins on the board.

If it's going to be permanent, just get a 8-pin SOIC breakout.

Never power something with a voltage divider. The current will be limited to the current rating of the resistors, which is normally very small (<1/2W).

The diode before the switch will drop around 1.7V going in to the motor. If you are keeping it make sure it can handle high currents since everything flows through it.

Join a club or a hackerspace near you. Also don't be afraid to ask if you can use your schools shop. If you want to do stuff at home, a lot of things can be made with hand tools and patience.

Yes, I was assuming you were asking for visually straight lines.

Perfectly straight lines at a large scale are pretty hard to find but the closest thing would probably be light. Light does 'bend' under gravitational force, however.

A 555 timer in monostable mode will work for this. Look for a power-on trigger circuit along with monostable operation.

Are you asking for an IC that will drive servos? An 555 timer with the right resistor-cap combination will work but servo control is usually done in software because of the varying pulse widths.

If there's no need for an analogRead variable then just directly substitute it into the if statement (if(analogRead(0)<=100)). It's not significant at all in something simple like this but it saves some processing cycles.

Hubble doesn't actually photograph color pictures by itself. It takes multiple photos with different wavelength filters in black and white, and then computers on the ground process that into a color picture.

Photo editors also change the RGB values slightly to fit the eye.

On the receiving end connect the rx and tx pins (pins 2 and 3 on the 328 I believe) to the usb-to-serial board and open up a com port on the computer. Make sure the baud rates are set to be the same.

You could try listening for a serial signal with pySerial on python. Send serial signals through USB (you're going to need a serial-to-usb ftdi board) and log it into a data file. If the thing isn't permanent, many serial terminals like coolterm have a log function that will work.

It would be better to use crystals anyway. They are much more accurate than ceramic resonators but you will need two capacitors on each pin for stabilization.

Calculate for pi to 10,000 digits. You can do this in python pretty easily with less than ten lines of code.
