My First Arduino-based Robot

My First Arduino-based Robot Finally, I managed to assemble my first Arduino-based robot. I bought it from this Italian online shop. They provide all the instructions as well, but you also need some tools (screwdrivers, soldering tool, etc.) and some patience. It works fine! Thanks to a quite basic IR sensor, this small rover can …

Recharge a 9V NiMh battery with a Solar Panel / Constant Current Generator

Hi guys, if you enjoyed the previous post solar-powered Arduino board, you should keep reading this one as well to improve your solar power generator. In fact, with that setup the 9V battery would decay too soon: A NiMh (Nichel - metal hydroxide) battery must be recharged with a constant current generator, a solar panel …

Temperature Measurement using Arduino and a Thermistor

Components Arduino Duemilanove Board, a USB cable and of course a PC/Mac A 10kOhm thermistor A 10kOhm resistor A breadboard wires Hot topic It'g getting hotter and hotter. Is it due to global warming? Who knows, but in the meanwhile we can measure the temperature with our Arduino board and a thermistor. A thermistor is …

Solar-Powered Arduino Board

Components Arduino Duemilanove Board 12V Solar Panel 1N4007 Diode 25V 100uF Capacitor 9V Rechargeable Battery and connector A breadboard and some wires (suggested red and black) A multimeter to measure tensions 1) Green Power Arduino datasheet suggests us to power it with 6-20V, being aware that the upper limit could be dangerous. It seems that …
