I was looking through schematics and board layout for a project to integrate a DOGXL160 onto an Arduino shield, and the DOGXL160 tech sheet, and found the power goes through a 100nF (nano-farad) 16V capacitor.<\/p>\n
Seems the “best match” I could find for this “teeny” spec component is a “surface mount technology” part. The idea of getting into SMT scares me, but from pictures I could probably take some of that solid core wire I’ve purchased and solder some small lengths on turning it into a very small “through hole” component.<\/p>\n
The power circuitry for the screen also needs some 2uF (micro-farad) 16V capacitors according to the spec sheet. The “shield” project specifies 2.2uF, so need some of those too.<\/p>\n
Finally on a “logic” level we need to buffer\/convert the Arduino 5V outputs down to 3.3V. We have four signals and we’ll follow the “shield” project by using four of the six lines of a “4050” level shifter.<\/p>\n<\/p>\n
I’ve decided against adding a touch screen to the project, as the connector I’d need is surface mount (see earlier for my thoughts on this). Net result is I need buttons. The tactile buttons I’m looking at right now come in packs of 20. That should do…<\/p>\n
All these things are “on order” now, but it dawns on me I must now be close to having all the “electronics” sourced. Need some more stuff for the MIDI side, and look at what I want to do beyond the breadboard testing stage. I think I need another breadboard too now I know I’ll be having probably a fair few buttons to worry about.<\/p>\n
I really should start thinking about the code and UI.<\/p>\n
