Hello,
I am fairly new to electronics and a first time poster so please be kind. I wish to create a circuit which sets off a row of solenoids one after the other. I have made an LED 555 timer circuit before but I understand that the voltages will be way too low for the solenoids or too high for the ICs.
Here is a circuit that I think is suitable:
I'm now going to make some crass assumptions on how I can modify it:
1. Change the LEDs to Solenoids
2. Have a high rail voltage so the solenoids work (this will also need to be varied to begin with so that the action of the solenoids is the correct stroke and strength)
3. Insert transistors between the solenoids and the 4017 IC and connect these to the higher rail voltage.
4. Insert a voltage drop resistor before 555 IC to protect both ICs
edit: these are the solenoids I have in question http://www.richmeg.com.tw/open_frame_solenoid_21_rgo1040l.html
Does what I've written make sense or am I grossly over simplifying things? Or is there a better / esier way to get what I want?
Many thanks
Thom
