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

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 … Continue reading Temperature Measurement using Arduino and a Thermistor
