Today we tried to build an H-bridge to control the motors.
We used TIP120 and TIP127 transistors and built the following circuit using 5V as VCC:
It did not work.
We are not sure if there was a problem with the connections – or if the circuit design itself as the problem.
Until next time, I will check the connections of the circuit and do some measurements. Eduardo will look at simulations to see if he can find any problems with the circuit there.
We’ll meet up in one week to continue building the robot.
