i have 6 wires from the controller of a RF car let's named them wire A B C D E F wire A B C are for forward and reverse wire D E F are for left and right when wire A connected with C, the car move forward when wire B connected with C, the car move reversed yes, i want to drive the transistor into saturation when the pin is turn on so can i use the circuit shown in the picture with some modification? the chip i use is Atmel 89S8253 and the port is 2 here is the chip datasheet: http://www.atmel.com/dyn/resou...oc3286.pdf i will change the BC547 to 2N3904 transistor case 1 the pin 1 of the transistor connected to wire A the pin 3 of the transistor connected to wire C the pin 2 of the transistor connected to port2 pin0 case 2 the pin 1 of the transistor connected to wire B the pin 3 of the transistor connected to wire C the pin 2 of the transistor connected to port2 pin1 Mathew |
