here are some guide on how to get started https://synthiam.com/Tutorials/Help.aspx?id=70

The board might be different but the concept is still the same, if more help is needed don't be afraid to ask.

I assume signal wires from 4 different Digital ports to each of the R_IS, L_IS, R_EN and L_EN. You can use 1 or 2 signal wires for PWM depending on if you want different speeds at different times.

Not quite sure what they do, sometimes you have a direction selector which could be the R_IS and L_IS, so high on R_IS and high on R_EN makes the one motor spin in one direction, low on R_IS and high on R_EN spins the other way.

Or

High on R_IS spins one way, High on R_EN spins the other.

Ask the seller for the instructions and wiring information to be sure.

Another tip: After you have EZB attached, do not attach your two output wires to your DC motors yet. Use a Digital Tester on the connection terminal blocks to see if your getting the proper voltages you are expecting. Forward and reverse.

Hi,

I don't understand this H Bridge. I tried with 4 wires

• GND
• VCC / +5v
• and each out (R_IS, L_IS, R_EN, L_EN, RPWM, LPWM) and it's didn' work.

I hadn't signal out. confused

I found this documentation, but it's chinese for me stress There is PDF and scripts.

What do you think about it ?

Thank you.

I don't understand how you have tried with 4 wires, how were they connected? What controls did you add or what script commands did you run?

Chances are you will need to apply a digital high to more than one pin for it to work.

You will probably find that without English documents nobody on here will be able to help you.

If you are willing to risk damaging the H-Bridge and possibly the EZ-B (I make no guarantees this is safe) you could try this.

Connect R_IS to the Signal of D19 Connect L_IS to the Signal of D18 Connect R_EN to the Signal of D17 Connect L_EN to the Signal of D16

Now add 4 Digital Toggle controls, set them to D19, D18, D17 and D16

See what happens when you turn on D19. What happens when you turn on D18. D17. D16... Then combinations of both. You may also need to apply a Signal wire to RPWM and LPWM. If you aren't fussed about individual speeds you can connect one signal to both pins. Then add a PWM control for the Pin(s) and move the slider to 100%.

If you don't want to risk your EZ-B you could simulate digital highs and PWM100% with 5v to the pins mentioned above.

In all cases you will also need to provide the H-Bridge a common Ground, an external Vcc for the motors and probably a 5V to the H-bridge.

But really, never buy a product that has no English (or whatever language you understand) data sheet.

I hope this help, try to make it as clear as possible and easy to follow. I use port D8, D9, D10, D11, D12 simply because they were easy to draw. feel free to adjust it to your personal needs. After some mild research I doubt this H-bridge can produce enough current to properly push your windshield wipers motors. D9, D10, D11, D12 can adjust via software to make it turn left and right properly. this concept should work.
