LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 1000 000 ohms, but when they are illuminated with light resistance drops dramatically.

This module is used for single-or multi-section parallel lithium lithium rechargeable battery, charging from the USB port to take power.
This module uses a very sophisticated charging chip TP4056 external circuit is simple, and good protection performance, high precision charging.
This module is fully mechanical automatic processing, the SMD parts manufacturing, each module will test before shipment, high reliability.
This module current self-regulation, as long as you change the fixed resistor in the circuit board, you can change the output caused 100mA-1000mA, very convenient.
This module is used for single-cell lithium or multi-section parallel lithium rechargeable battery, charging port to take power from the USB or pins.
Test current ammeter can only be connected in series with the 5V input of the charge sheet.
Charging current best to be 0.37C of the battery capacity, which is the capacity of 0.37 times, such as the 1000mAH battery charging current 400 this is enough. Too fast charge effect poor, rushed over battery voltage out more!
Charging connector wire can not be too small and too long. This connection resistance. Too fine red over battery voltage out.
Connected to the battery best good contact. Or red over battery voltage out.
If input volt over 5V, such as 5.2 or 5.5, will result in less than 1000mA charging current, this is normal. High voltage chip the fever will automatically reduce the charging current, not to chip burned. About 60 degrees in the work, the chip heat is normal. After all, the charging current is large.
Input reverse the chip has no effect, but the output (battery terminal) the reverse will burn chip, please note that.
