I designed this “USB Freeform Arduino” with USB connector to be enclosed inside a 35mm film canister.
The biggest challenge is how I couid fasten the “none PCB Arduino” to it own enclosure, in this case cylinder shape canister?
The answer was not an easy one. But the solution I found was an easy thing to do, and it was an excellent solution that we quite familiar with.
“How about glue it in!”, I said to myself.
Step 1: Parts and Tools
Schematic shown below is comprised of the minimum components and could be used FTDI cable to upload the sketch.
On the actual USB Freeform Arduino did not included the 1K resistor and 3mm LED that connected to pin D13 as in the schematic.
These are the minimum components to get Arduino up and running.
(1x) ATmega168/328 preloaded with Arduino Bootloader
(1x) 16 Mhz Resonator
(2x) 0.1uF Ceramic Capacitors
(1x) 3mm red LED (Only needed for testing purpose only)
(1x) 1K Resistor
(1x) 10K Resistor
(1x) 6-pin Male Header (as the connector to FTDI cable to upload the sketch)
(2x) 1×14 Female Receptacle
35mm Film Canister
USB Standard type A cable (Male Connector)
Solder iron and Solder station
Micro drill bit for Hand drill
