Micro Slave

Wellicht een tip voor de kleinbehuisden onders ons, de micro slave:
(in dit geval een draadloze lichtmeter)

Op basis van een Atmel Tiny85. Zend de data door als variabele naar de Mega nodo. En die weer naar de webapp.
Beetje jammer dat de DC plug zo groot is, bijna de helft van de schakeling

Je bent goed bezig :D
Is deze ook te programmeren met behulp van een arduino?

Is eenvoudig te programmeren met een Atmel328 voorzien van de Arduino ISP sketch. Ik heb zelf even een programmer in elkaar gezet. Ook handig om bootloaders te updaten of fuses te wijzigen via avrdude.

Vervolgens moet je een zipfile downloaden met de hardware configs voor de Tiny45/85 zodat de Arduino IDE hiermee overweg kan. e.e.e is uitvoerig op diverse sites beschreven. Even googlen op 'Arduino IDE tiny85'.

Je kan natuurlijk elke ISP programmer gebruiken, ook een Arduino Due of UNO (Bij de UNO moet je wel wat tweaken met weerstanden/condensator aan de reset pin). Is ook overal uitgebreid beschreven.

Ziet er goed uit.. Ik heb zelf ook wat tiny's besteld.
Ik kwam dit: tegen.

Lijkt mee een mooie aanvulling. Voor een paar centen heb je een micro slave. Net als jouw uitvoering. Zei het niet dat deze door een 2032 gevoed wordt. Dit spreekt mij helemaal aan.

Ik ben al wat voorwerk aan het doen, heb ze nog niet, maar vroeg me af wat voor sketch jij hiervoor gebruikt? Aangezien serial niet wordt ondersteund door de tiny (geen rx tx pins)?
Hoe heb jij de nodo code werkend gekregen? Of heb je een versie waar je de hele serial hebt uitgegooid?
