Solar NiMh with Arduino

Post by pixeltx »

Does anyone have a simple circuit for a smart solar NiMh battery charger using an Arduino ? I'm trying to create a simple self charging led light using solar and NiMh batteries similar to a garden light but more robust, 4 x AA and 3 or 4 high brightness LED and seems trickle charging is too slow for 5 hours sun, I'm using a 1.5 W solar panel 6 volt (I'm actually planning to move the design to a trinket to reduce cost)
