So what kind of bridge would you recomend?
I'm using 2 Brushed DC Motors
Motor details:
- Operating Voltage: 3V ~ 6V DC
- Recommended Operating Voltage: about 3 to 6V DC
- Load Current: 70mA (250mA MAX)
- No-load Speed: 1:48 (3V)
IO pins 2,3 are connected to H-Bridge inputs A1, A2,
IO pins 4,5 are connected to H-Bridge inputs A3, A4
H-Bridge outputs
Y1,Y2 connected to left DC motor
Y3,Y4 connected to right DC motor
5V arduino is connected to H-Bridge Vcc1 for logic
6V battery connected to Vcc2 for power supply
The spec sheet at
says:
"The L293D is designed to provide bidirectional drive currents of up to 600-mA
at voltages from 4.5 V to 36 V."
What do you mean that it loses everything up to about 3V?
