    need help to control this

    sorry my schematic has a typo the power supply is 10v and the voltage at the terminals is correct ie if I do analoguewrite 255 to the output of my arduino i get 10v at the connections if I write 130 to the pin I get 5v at the terminals etc. this is only if I take out the capacitor. If I put in...

    need help to control this

    I want to use pwm from an arduino to control this http://uk.farnell.com/jsp/search/productdetail.jsp?SKU=1936419 It is a solid state relay with proportional control and needs 2-10v to operate. I need a circuit design to convert the 0-5v pwm to 2-10v analogue. I have tried using a transistor...

    bridge rectifier help

    But i am testing at the terminals where the a/c comes in and i am getting 9v a/c surely this would be 14v as well on open circuit.

    bridge rectifier help

    I have just completed a bridge rectifier which I want to use to power my arduino from a 9v ac power supply. I have fitted a 6800uf 10v capacitor across the pos and neg. when testing it I found that I have 19v dc across the pos and neg. any ideas to what I have done wrong. I have not tried it...
