Is my shematics good ? Answered
Hi there !
I have the project to make a trash compactor. To do this i have a truck wiper motor http://ncr.en.alibaba.com/product/319740439-215097357/180W_Bus_wiper_motor_EMI_EMC_Volvo_bus_wiper_motor_12_24V_NCR_8385_.html ( 180W 24V 30A ) and a worm screw sytem.
To control this motor, i've made a H bridge with this transistors https://www.sparkfun.com/products/10213
To control the intensity consumed by the motor and prevent it from burning, i use a current sensing chip http://http://www.evselectro.com/kits-30a-range-acs712t-elc-30a-module-current-sensor-module-3024
To control all of that, i use ATTiny 84.
My power suplly is 24V 30A and my µC ( The ATTiny 84 ) use 5v suply so i have to convert a part of the 24V to 5V. To do that i use 7805 but i think it will burn or i will lose lot of energy.
I've made the shematics of my circuit and i wonder if it's good or not and what can i change.
PS: The two switch in the schematics are end positio sensor.
Thank :D and sorry for my bad english :/
