40W Choke Board  
The shortcoming of the inductive ballast is that volume and weight are larger, one's own power consumption is great, there are noises. The electronic ballast has low-voltage starter, non-stroboscopic, has no noise, energy-efficient, immediate advantage in the lighting twinkling of an eye, so the electronic ballast has broader development space

L293D_Motor Driver  
L293D is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors.
