Design a circuit for a flashlight
$250-750 USD
Paid on delivery
This project is to design a circuit board to control a flashlight. The circuit board will be responsible for charging the lithium polymer battery and control the brightness of the LED. This circuit must incorporate a micro-USB port, lithium polymer battery protection, and allow for 3 different lighting intensities. The rough bounding box size for this circuit is 36 X 12.5 X 4 mm. A momentary switch will be used to cycle through the power modes. Thank you!
