LM3916 Vu meter Circuit Indicator rna 10-point reading field made of LEDs. The diodes were scaled in dB, transmitting irn, from D4 to D13, respectively, the following weights: -20 dB, -10 dB, -7 dB, -5 dB, -3 dB, -1 dB, 0 dB, +1 dB, +2 dB, +3 dB. The LED indicator may work in line…

Voltage, Current, Temperature, Power and Load Resistance Measurement

| 2020/04/03

In addition to measuring voltage, current, power and temperature, the meter can also calculate the resistance of an attached load. However, this is not the most important difference – more importantly, this meter can also measure negative voltage and current. Recommendations: the meter can be used in a laboratory power supply or other power system.…

DMX Servo Driver Circuit

| 2020/04/02

The ATmega168 project is a continuation of devices with DMX interface designed for set designers, people involved in the setting of events, musicians, etc. Our controller is able to control four servos, with which you can, for example, control lighting or animated elements of the scenery. After the transmission decay, the servos may be in…

Lighting switch in the garage

| 2020/04/02

Driving a car into the garage after dark can be fatal if it has no lighting. The presented system automatically switches on the lighting, without leaving the vehicle. He will also remember to turn them off later. The switch system is designed for 230V AC supply. It works by detecting a beam of light (coming…
