Arduino

Introduction

Some Arduino related stuff.

Use e.g. Cool Term Win to save logged terminal data from serial monitor. The serial monitor need to be closed during the recording.

Tutorials. Arduino Cansat project. See also https://github.com/markkuleino/cansat/. See jumpers

When J2 and J3 are not connected, you can program the Arduino via the USB cable.
By setting the jumpers at J2 (and J3) you can transmit data through the radio.
When placing jumpers at J4 (and J5) you enable data storage in the MicroSD-card (if a MicroSD card is inserted).
When placing a jumper at J6, the EN pin on the APC220 radio module is connected to the digital port D7 on the Arduino.
A jumper must be placed either at J7 or at J8 or both in order to connect power to the Gy-87/88/91.

Projects

Check the pins while uploading, saving or using memory card.

1. CanSat-laajennuspiirilevyssä on oikeanpuoleisen kuvan mukaisesti kaksi hyppyjohdinsarjaa, J2 ja J3.
2. Kun J2- ja J3-hyppyjohtimia ei ole kytketty, voit ohjelmoida Arduinoa.
3. Kun asetat hyppyjohtimet kohtiin J2-1 ja J2-2, voit lähettää tietoja radiolla.
4. Kun asetat hyppyjohtimet kohtiin J3-1 ja J3-2, voit ottaa käyttöön tietojen tallentamisen SD-kortille (jos se on kytketty).
