Hi everybody, im new to the site. Im looking for a project for my final term of my electrical apprentiship. Im on the hunt for a lighting circuit that incorporates a variable brightness in relation to the surrounding ambient light. The light when switched in the on position would be at full brilliance in complete ambient darkness, half brillience at dusk or dawn situation and not come on or minimul output at full ambient brightness.
For some reasons ive searched and searched and cant seem to find a decent circuit drawing that would work for my idea. Im assuming i need an LDR or multiple ones scrs and op amp but i dont know where to start. im in an Advanvced electronics class but my level is certainly not advanced. also id like to use a 12 volt dc auto tail lamp if i could. This project is just a plug and play proto bread board type.
If any one has any suggestions or even better a working circuit diagram. id greatly appreciate it.
Thanks in advance.
