Title: Make Your Own Arduino
Class Size: 5-6?
Cost: $20 (+$5 for FTDI adapter, or bring your own, or use ours as long as it doesn't leave the building)
Pre-requisites: none, though having a laptop to try programming the board would be helpful.
Minimum Age: 12 and up (under 18 must have parent present)
In this class, Students will learn to solder their own Diavolino Arduino clone. No previous soldering skill needed. Some simple programming will be done after the board is assembled.
Outline:
- Full instructions at http://s3.amazonaws.com/evilmadscience/KitInstrux/diavolino_instrux.pdf
- Resistors
- 1K
- 10k
- IC socket
- Orientation! (less necessary than the IC itself, but good to get in the habit of doing this correctly)
- Tack first pin in, then adjust fit as needed
- Capacitors
- 18pF (2) (have black splotch across the top)
- .1 uF (3)
- Switch
- LED - Square Hole + (long lead)
- Crystal (*outer* holes on the PCB)
- Programming header
- tack in pin and adjust if necessary
- Microcontroller
- ORIENTATION CRITICAL
- Jumpers (somewhat optional)
- NOTE: The Diavolino does not have any protection from multiple voltage sources. You *must* be a little careful when powering it. If using USB power, TURN THE BATTERY PACK OFF!
- USBV Jumper - if you don't want to use the battery pack, or want it to be powerable via USB, install this jumper.
- Regulator jumper- if you want to use a 5V wall power supply, you can install this jumper. If you want to use a 9V (or greater) power supply, DO NOT INSTALL THIS JUMPER.
- Battery Pack (optional)
- Use the holes near the solder points for strain relief on the cables
- Pack can be foam-taped to the underside of the board, if you want
- Headers
- Solder these carefully- proper alignment is important!
- Tack one pin of each on, then adjust as necessary
- Power on test
- Apply power (via batteries or USB)
- The LED should begin blinking at a 1 second on, 1 second off rate.
Upgrades/Hacks:
- Voltage Regulator - if you install a 2.1mm power jack, a L7805 voltage regulator, and a 0.1 uF and 10 uF capacitor, you can power the board from a 9V+ wall power supply.
